Essay 1
A group of researchers conducted an experiment to determine which vaccine is more effective for preventing getting the flu. They tested two different types of vaccines: a shot and a nasal spray. To test the effectiveness, 1000 participants were randomly selected with 500 people getting the shot and 500 the nasal spray. Of the 500 people were treated with the shot, 80 developed the flu and 420 did not. Of the people who were treated with the nasal spray, 120 people developed the flu and 380 did not. The level of significance was set at .05. The proportion of people who were treated with the shot who developed the flu = .16, and the proportion of the people who were treated with the nasal spray was .24. The calculated p value = .0008.
For this essay, describe the statistical approaches (e.g., identify the hypotheses and research methods) used in this excerpt from a research study. Interpret the statistical results and examine the limitations of the statistical methods. Finally, evaluate the research study as a whole and apply what you have learned about hypothesis testing and inferential statistics by discussing how you might conduct a follow-up study.
Your essay must address the following points:
• Describe the research question for this experiment. o What were the null and alternative hypotheses? o Were the results of this test statistically significant? o If so, why were they significant?
• Would the researchers reject or fail to reject the null hypothesis?
• Do the results provide sufficient evidence to support the alternative hypothesis?
• Was the sample appropriate for this study? Explain

...ork2012 - 2013 Catalog A Message from the President “Sullivan University is truly a unique and student success focused institution.” I have shared that statement with numerous groups and it simply summarizes my basic philosophy of what Sullivan is all about. When I say that Sullivan is “student success focused,” I feel as President that I owe a definition of this statement to all who are considering Sullivan University. First, Sullivan is unique among institutions of higher education with its innovative, career-first curriculum. You can earn a career diploma or certificate in a year or less and then accept employment while still being able to complete your associate, bachelor’s, master’s or doctoral degree by attending during the day, evenings, weekends, or online. Business and industry do not expand or hire new employees only in May or June each year. Yet most institutions of higher education operate on a nine-month school year with almost everyone graduating in May. We remained focused on your success and education, and continue to offer our students the opportunity to begin classes or to graduate four times a year with our flexible, year-round full-time schedule of classes. If you really want to attend a school where your needs (your real needs) come first, consider Sullivan University. I believe we can help you exceed your expectations. Since words cannot fully describe the atmosphere at Sullivan University, please accept my personal invitation to visit and experience...
