You need to set the clock to the correct time. What time do you set it to? Think about the fact that the blue section is 1/4 of a circle. Hint: Enter your answer using a : for the time instead of a decimal. For example 9.42 would be entered as 9:42. * Let's take a closer look at the clock face. You need to find the area of the area shaded in blue. It has a radius of 4 inches. Use 3.14 for pi.

(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.)
