Do part b of Exercise 9.15 if the sample mean equals 60.262.
In par b exercise
Suppose that Consolidated Power decides to use a level of significance of a .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 that the population standard deviation equals 2.
