One Sample Hypothesis Test Essay Example for Free

One Sample Hypothesis Test Essay Earning potential and income of every person is severely different; many factors have a hand in determining the amount of money a person makes and how much his or her earning potential can increase. Some of the factors currently determining the earning potential of people around the United States are; education, marital status, age, union participation, race, age, years of experience, sex, the industry in which the individual works, and the position held by individual. This paper is going to show the correlation between marital status and income, the team has disregarded all other determinants to answer the research question clearly. The research question that the team has developed and the hypothesis was formed from goes as follows; does marital status affect earning potential? Every decade that passes, it seems as though people are waiting longer to get married. Waiting for job security, completion of college and social norms are just a few factors that influence this trend. This is a big change from 50 years ago, when most people would get married straight out of high school. The fact is being single has some advantages when deciding to start a career, it also affects ones earning potential. Being single allows more dedication to the job as well as the mobility to go wherever the job may take an individual. While being single may be good for starting a career, being married will actually increase a person’s earning potential in the long run. The mean salary for the single person is $24,864 per year. The mean income for married individuals is $33,303. This leads us to our null hypothesis (H0) that being married will not improve the earning potential of an individual. Our alternate hypothesis (H1) is that being married will help improve the earning potential of an individual. Numerically it is stated: H0: ÃŽ ¼1 ≠¤ ÃŽ ¼2 H1: ÃŽ ¼2 ÃŽ ¼2 The five-step hypothesis test starts with stating the null and alternative  hypothesis. The null is H0: ÃŽ ¼1≠¤ÃŽ ¼2 and the alternative hypothesis is H1: ÃŽ ¼1ÃŽ ¼2. The second step in find the decision rule. The decision rule is reject H0 if ÃŽ ¼1 ÃŽ ¼2 ÃŽ ¼1. Step 3 is to calculate the test statistics. It has come to the mean of the earning potential of those who are married and those who are unmarried. Married couples have a mean salary of $33,303.00 and unmarried individuals have a mean salary of $24,864.00. Step 4 is to compare the test statistics to the critical value. The test results in married couples have a greater income than the salaries of unmarried people. Step 5 is to state the results. In result, married couples have greater earning potential than that of their unmarried counterparts. Therefore, in this case the team has to reject their null hypothesis because they have discovered a greater earning potential for married couples over unmarried individuals. The team’s results provided support to the null hypothesis that a married individual has a higher earning potential than that of a single individual. As previously stated a single individual on average makes $25, 000 while married individuals make on average $34,000 a year. Our research also indicates more working individuals are married over single. Our sample only included 33 single and 67 married individuals. Our study also found non-married men have wages that range from $11,000 to only $27,000 while non-married females wages range from $15,000 to $83,000. Married men have wages that range from $28,000 to $84,000, married women however only have wages that range from $11,000 to $50,000. This shows independent women with one sole income on average make more than men. However, after marriage, the men tend to become the higher wage earner. Education does not appear to play a significant role it ranges from four to 18 years. A married man with 18 years of education can made up to $84,000 while a single man also with 18 years of education only made $27,000. That is in contrast with a single woman with 17 years of education who make $83,000 a year and a married woman with 17 years of education who made $34,000. The maximum wage for a married woman was $50,000 and this was with 12 years of education. We analyzed many different aspects of earning potential and the majority proves a married individual will make more than that of a single individual. With all of the numerical data analyzed, the research question answered, and the hypothesis being correct, the team has been able to state confidently that marital status drastically affects  earning potential. On average, those who are married make nearly $8,500 more than those who are unmarried. Several other factors determine the income potential differences, but without further analyses of data not provided in the data set, the team would just be throwing around assumptions on the matter.

Coral Reefs And Bleaching Phenomenon Essay -- essays research papers

Imagine yourself observing one of the most diverse ecosystems on earth. Thousands of species of plants and animals provide a dizzying array of color and motion. Massive structures provide a canopy that shelters hundreds of exotic species in a myriad of microclimates. As land-based observers, we almost automatically assume that this is a description of the rich ecosystem of a tropical rainforest. However, if we take ourselves off the safety of dry land and immerse ourselves in the ocean, we will find an equally dynamic environment in the depths of our world’s coral reefs. As a Zoology major, I quickly decided to explore this biological component of the ocean environment. In the following paper, I will provide a general overview of coral reefs and examine the alarming depletion of coral and their ecological symbionts in a process known as coral bleaching.   Ã‚  Ã‚  Ã‚  Ã‚  As mentioned earlier, coral reefs are among the most diverse and productive of all communities on Earth. They are also the largest biological structures on the planet. The Great Barrier Reef, along the eastern coast of Australia, covers over 2000 kilometers and is said to be visible from the moon (Goreau, 1987). While the size of coral reefs can be enormous, their real impact is on a much smaller scale. Reefs function as food and shelter for fish and marine invertebrates. While the coral itself is an animal, through a symbiotic relationship with the unicellular algae, coral becomes the primary producer in its ocean ecosystem (Richmond 1993). The reefs are formed by calcium carbonate deposits produced by the coral polyps. According to the legendary Cousteau, in his book The Ocean World, tube worms and mollusks also donate their hard skeletons to the architecture of the growing reef (174). Biologically active compounds are also produced by reef dwelling organisms an d posses antimicrobial and antiviral properties (Van Alstyne 1988). In fact, coral produces a natural sunscreen that is currently marketed and also holds promise in generating chemicals for AIDS and cancer research. In 1995, researchers mimicked the structural components of coral and now use the patented super hard compound to repair shattered human bones (Alderage 1995). Further more, coral reefs are naturally extremely productive fishing grounds. In fact, healthy reefs produce up to 10-100 times more yield per unit a... ...pear, the fate of one of the world’s most diverse ecosystem remains to be seen. Bibliography Alderage, Susan.

Together with the Indian state of  West Bengal, it makes up the ethno-linguistic region of  Bengal. It is the  eighth most populous country and among the  most densely populated countries  in the world. Bangladesh is in the low-lying Ganges–Brahmaputra River Delta or Ganges Delta. The Ganges unites with the Jamuna and later joins the Meghna to eventually empty into the Bay of Bengal. We have lots of natural elements. In this term paper we want to describe about the beauty of our country. 2. 1 Heritage sites 2. 1. 1. Shat Gambuj Mosque It is a Tughlaq styled mosque. Khan Jahan Ali  was the architect and  general contractor of this historical mosque. It is the largest  historical mosque  in Bangladesh. It is also one of the most impressive  place on the Indian Subcontinent. The mosque is situated on the eastern bank of the Ghora Dighi. The name Shat Gambuj Masjid means a mosque with sixty domes. But  actually the mosque has 77 squat domes with 7 four sided pitched  Bengali domes in the middle row. The mosque is constructed in 1449 with terracotta decoration. Around the doors you can see beautiful design. Inside of the mosque the walls are designed by former muslim cultural tradition. The full  mosque is a wonderful archeological beauty which is the signature of  the 15th century. 2. 1. 2. Mahasthangarh [Bogra] Mohasthangarh is one of the main attractions in north Bengal. It was the capital of Kingdom of the Mourjo, the Gupta and the Sen Dynasty. This is the ancient archeological and historical which was, established in 2500 BC. It is the oldest archaeological site of Bangladesh is on the western bank of river Karatoa 18 km. The spectacular site is an imposing landmark in the area having a fortified, oblong enclosure measuring 5000 ft. by 4500 ft. with an average height of 15 ft. from the surrounding paddy fields. This 3rd century archaeological site is still held to be of great sanctity by the Hindus. Every year (mid-April) and once in every 12 years (December) thousands of Hindu devotees join the bathing ceremony on the bank of river Karatoa. 2. 2 Country Of longest beach and World's Largest Mangrove Forest 2. 2. . Cox's bazar To the south of Chittagong, Cox's Bazaar is the tourist capital of Bangladesh. Having the world's longest unbroken (120 km) beach sloping gently down to the blue waters of the bay of bengal against the picturesque background of a chain of hill covered with deep green forests. Cox's Bazaar is one of the most attractive tourist spots in the world. Miles of golden sands, towering cliffs surfing waves, rare conch shells, colorful pagodas, Buddhist temples and tribes, delightful seafood – these are specialties of Cox's Bazaar. The beach is good for bathing, sunbathing and swimming. The breath-taking beauty of the sun-setting behind the waves of the sea is captivating. Visits to the fascinating picnic spot at Himchari, Teknaf are amazing. Buddhist temple at Ramu and nearby island of Sonadia, St. Martin and Mohaskhali are memorable experience of one's lifetime. 2. 2. 2. Sundarban The Sundarbans delta, at the mouth of the Ganges river, is the largest mangrove forest in the world, spreading across parts of Bangladesh and West Bengal, India. The Sundarbans features a complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests. The area is known for its wide range of fauna, with the Royal Bengal tiger being the most famous, but also including many birds, spotted deer, crocodiles and snakes. Tiger is the greatest parts of the Sundarbon and they are very powerful. Bengal tigers are very attractive in the worlds demand. So many tiger exist in the world but Rayal Bengal Tigers are very demanding here for their extra ordinary activities of their own. 2. 3. Cultural Beauty 2. 3. 1. Pohela boishakh: The first day of Bangla year is called Pohela Boishakh or Bangla New Year. It is the first day of the Bengali calendar celebrated in both Bangladesh and West Bengal and Bengali communities in Assam and Tripura. . â€Å"Celebrations of Pohela Boishakh started from Akbar's reign. It was customary to clear up all dues on the last day of. On the next day, or the first day of the New Year, landlords would entertain their tenants with sweets. On this occasion there used to be fairs and other festivities. In due course the occasion became part of domestic and social life, and turned into a day of merriment. 2. 3. 2. Lalon Akhra: Fakir Lalon Shah is also known as Lalon Shah (c. 774–1890), was a Bangladeshi philosopher poet. His poetry, articulated in songs, is considered classics of the Bangla language. Fakir Lalon Shah lived in the village of Cheuria in the district of Kushtia and to the Upazila(sub district) of Kumarkhali in Bangladesh. The details of Lalon's early life are made controversial mainly by urban-educated scholars representing communal tendenc ies among both Hindu and Muslim writers. Lalon also recorded very little information about himself. Depending on the source, some claim Lalon was born of Hindu Kayastha parents and during a pilgrimage to Murshidabad with other Bauls of his native village; . 4. Some Other Natural Beauty 2. 4. 1. River and river side: Bangladesh is a land of rivers. Many of these rivers are wide and long. The bank of the river presents an unbroken view of a variety of sights which entertain the eyes. Here men, women and children bathe, there women get down to water’s edge with pitchers in their hands and again there washer man wash clothes and cowboys graze their cattle. A river offers a grand spectacle on a moonlit night. All around there is a deep silence which is now and then broken by the splashing dip of oars and the songs of the boatman. . 4. 2. Paddy Field: A paddy field is a flooded parcel of arable land used for growing rice and other semi aquatic crops.. Paddies can be built into stee p hillsides as terraces and adjacent to depressed or steeply sloped features such as rivers or marshes. During the twentieth century, paddy field farming became the dominant form of growing ricePaddy field looks different in different colors. When it is green the land turns into a carpet of bright green rice shoots while the smell of drying jute invades the air. And when it is yellow then the paddy field looks like gold. . 4. 3. Six Seasons and Six Beauties: At an interval of every two months, there appears a new season in Bangladesh. Thus we have six seasons in Bangladesh. They are summer, the rainy season, autumn, the late autumn, winter and spring. March to May or in Bengali Baishakh and Jaistha are the Summer months. Summer is the season of scorching sun. It is the season of perspiration and thirst. Then comes the rainy season. The months of June to August or Asharh and sraban make the rainy seasons. In this season the sky remains cloudy and it rains day and night. Rivers, tanks, ponds and canals are full of water. The autumn rolls into Late autumn or Hemanto, which is the seasons of dew. Harvesting of crops begins soon. The golden paddy in the fields creates in the minds of the peasants many happy dreams. From mid-November to early January, the weather becomes more arid and less humid. The earth dries and dust forms. Warm clothes are pulled out. Young people play tennis, football, cricket and golf. The coolest days are from mid-December to February when the days are golden with light, the flowers are blooming and the nights and early mornings are chilly. Night guards wrap themselves up in shawls and blankets with scarves and hats are pulled down over their ears. 2. 5. The potential travel and tourism services in Bangladesh 2. 5. 1. The potential of the tourism industry The tourism industry is quite a young line of business in Bangladesh, where the development predominantly has been left to the local market forces. Today this market has both local and international tourist players competing for the small existing market, primarily composed of a local tourist market and a foreign business market. Bangladeshi government and private tourist sector are represented by organisations, nevertheless co-operation, strategies and policies aiming at developing a prosperous and sustainable tourist industry are rare – and not always implemented if they exist . To develop the Bangladeshi tourism industry successfully a local based strategy is crucial – without visions, missions, goals and policies for this line of business the development is largely uncontrolled. Here by there is a possibility that an undesired or destroying tourist development takes place, often being influenced by powerful foreign tourist players. . 5. 2. Future tourist demand Bangladesh is part of South Asia, which also includes Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. This major region is the most under represented region in tourism terms, with 23 per cent of the world’s population but less than 1 percent of staffers. We have lots of natural elements. We need to care our nature. We h ave lots of opportunities to increase our tourist demand. We can introduce our self as a tourist country. We have longest beach and mangrove forest and lots of natural elements of beauty. We can advertise our self as a most beautiful country in world 3. 1. Conclusion: It is not possible to describe the beauty of Bangladesh in some paper. We have lots elements of our natural beauty. I hope I will never find any country as Bangladesh.

Understanding Business Research Terms and Concepts Anna M Teffeau RES/351 - BUSINESS RESEARCH 6/30/2014 Annette West Understanding Business Research Terms and Concepts There are many different types of quantitative data collection instruments and sampling methods available to researchers. The ones that I have picked for the purpose of his paper are questionnaire, sampling and surveying. Each can be a value to a researcher when completed with accuracy. Validity is the degree to which an instrument measure what it is purports to measure. Invalid instruments can lead to erroneous research conclusions, which in turn can influence educational decisions. Reliability is the internal consistency or stability of the measuring device†¦show more content†¦When analyzing data, such as the marks achieved by 100 students for a piece of coursework, it is possible to use both descriptive and inferential statistics in your analysis of their marks. Typically, in most research conducted on groups of people, you will use both descriptive and inferential statistics to analyses your results and draw conclusions. So what are descriptive and inferential statistics? And what are their differences? Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Descriptive statistics do not, however, allow us to make conc lusions beyond the data we have analyzed or reach conclusions regarding any hypotheses we might have made. They are simply a way to describe our data. Descriptive statistics are very important because if we simply presented our raw data it would be hard to visualize what the data was showing, especially if there was a lot of it. Descriptive statistics therefore enables us to present the data in a more meaningful way, which allows simpler interpretation of the data. For example, if we had the results of 100 pieces of students coursework, we may be interested in the overall performance of those students. We would also be interested in the distribution or spread of the marks. Descriptive statistics allow us to do this.
