(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.)

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

If a company produces x units of an item at a cost of $35 apiece the function c=35x is a of the total production costs
