Specifications for steel plate to be used in the construction of a certain bridge call for the minimum yield to be greater than 345 MPa. Engineers will perform a hypothesis test to decide whether to use a certain type of steel. They will select a random sample of steel plates, measure their breaking strengths, and perform a hypothesis test. The steel will not be used unless the engineers can conclude that μ> 345.

a. Assume they test null hypothesis H0: versus H1: Will the engineers decide to use the steel if H0 is rejected? Will the engineers decide to use the steel if H0 is not rejected?

b. Assume the engineers test H0: versus H1: Will the engineers decide to use the steel if H0 is rejected? Will they use the steel if H0 is not rejected?
