1. Using the sample data, perform the hypothesis test for each of the above situations in order to see if there is evidence to support your manager’s belief in each case A–D. In each case, use the Seven Elements of a Test of Hypothesis in Section 6.2 of your text book with α = .05, and explain your conclusion in simple terms. Also, be sure to compute the p-value and interpret. 
2. Follow this up with computing 95% confidence intervals for each of the variables described in A–D, and again interpreting these intervals. 
3. Write a report to your manager about the results, distilling down the results in a way that would be understandable to someone who does not know statistics. Clear explanations and interpretations are critical.
