(2) Consider the problem of testing H. : µ > 100 against Ho : µ = 100 at the a = 0.05 level, given that you have observed 7 = 102.8 and s = 10.9 from a random sample of n = 55 individuals. (You may assume that the population is approximately Normally distributed.) (a) Come up with a “real world situation" that could motivate performing this partic- ular test. (b) What are the results of the test? What is the p-value? (c) Would the answers to (b) be different if we had used a = 0.01 instead, all else being equal. Explain why or why not? (d) Would the answers to (b) be different if we had used n = 45 instead, all else being equal. Explain why or why not? (e) Would the answers to (b) be different if we had used H. : µ # 100 instead, all else being equal. Explain why or why not?
