(b) 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 = 61.296 test Hy 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 0 = 6. (Round your z to 2 decimal places and p-value to 4 decimal places.) p-value Reject HO. So the plant should be shut down and the cooling system repaired
