For numbers 4a-4d, Choose Yes or No to indicate whether each equation is correct..
4a. 300 divided by 25 = 1
4b. 333.3 divided by 11 = 30.3
4c 1,440 divided by 32 = 45
4d. 1,725 divided by = 25 = 69.1

(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.)
