Consolidated Power, a large electric power utility, has just built a modern nuclear power plant. This plant
Question:
a. Consolidated Power wishes to set up a hypothesis test so that the power plant will be shut down when the null hypothesis is rejected. Set up the null hypothesis H0 and the alternative hypothesis Ha that should be used.
b. Suppose that Consolidated Power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. If the sample mean of the 100 temperature readings is = 60.482, test H0 versus Ha and determine whether the power plant should be shut down and the cooling system repaired. Perform the hypothesis test by using a critical value and a p-value. Assume σ = 2.
