(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 7=60.990, test He versus H 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 value. Assume o 5. (Round your z to 2 decimal places and p value to 4 decimal places.) powe (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 7=60.990, test He versus H 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 value.
