2. A manufacturer informs a customer's design engineers that the mean tensile strength of its rivets is at least 3000 pounds. A test is set up to measure the tensile strength of a sample of rivets, with the null and alterna- tive hypotheses, H0: µ $ 3000 and H1: µ , 3000. For each of the following individuals, indicate whether the person would tend to prefer a numerically very high (e.g., a. 5 0.20) or a numerically very low (e.g., a. 5 0.0001) level of significance to be specified for the test.

a. The marketing director for a major competitor of the rivet manufacturer.

b. The rivet manufacturer's advertising agency, which has already made the "at least 3000 pounds" claim in national ads.
