room is a rectangular base prism with 27ft by 25ft and height of 15ft. A volleyball is 8 inches in diameter. How many volleyballs are needed to fill his room. 1 ft = 12 in. Packing Space is 190%.

(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.)
