Would you please explain in full detail, a minimum of 3 pages? One page for each. 1) A hypothesis is a claim about something about a population. Think about a career in the health care. What are some examples of hypotheses that you would be interested in testing? Give an example describing your situation, including the null hypothesis and the alternative hypothesis. 2) The freshman 15 refers to the urban legend that students gain an average of 15 pounds during their freshman year of college. The weights of 100 freshmen at a certain University were observed in August and then re-examined in May. The claim that the mean difference is equal to 15 pounds is tested at a 0.05 significance level. The result is "fail to reject the null hypothesis". What do the results suggest? What factors could have affected the results? How can these results be used to make changes on campus? 3) In a test of a weight loss program, weights of 40 subjects are recorded before and after the program. Assume that the before/after weights result in r = 0.876. Is there sufficient evidence to support a claim of a linear correlation between before/after weights? Does the value of r indicate that the program is effective in reducing weight? Why or why not
