Critique Jamie's work by explaining the reasonablleness of the scenario and the accuracy of the two parts of the graph he described. For any portion of Jamie's response in which he has made an error, provide and explain an alternative response. To enhance Jamie's explanation, describe both sections of the picewise function using linear equations. Include any limits to the domain.

(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 x⎯⎯ = 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 σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
