Refer to a study of the factors that lead to successful performance-based logistics projects. Recall that opinions of a sample of Department of Defense (DOD) employees and suppliers were solicited during interviews. Data on years of experience for the 5 commercial suppliers interviewed are listed in the accompanying table. Assume these 5 interviewees represent a random sample selected from all DOD commercial suppliers. Consider the claim, "On average, commercial suppliers of the DOD have 5 years of experience.". Using a=.05 X- 30 10 10 a. Calculate the z-score for x=15 b. Calculate the confidence interval for the population mean c. What is the rejection region for the hypothesis test? And use the rejection region to state the appropriate conclusion for the hypothesis test.
