(b) suppose that consolidated power decides to use a level of significance of Ξ± = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is xβ―β― = 60.990, 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 Ο = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
