A tennis court is surrounded by a fence so that the distance from each boundary (edge) of the tennis court to the fence is the same. If the tennis court is 78 feet long and 36 feet wide, what is the area of the entire surface inside the fence?

(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.)
