Aball is dropped from a height of 20 feet. after the
first bounce its peak height is 12 feet. with each
bounce, its peak height is 60% of the previous
peak
identify the height of the ball after one, two, and
three bounces
height after one bounce:
feet
height after two bounces
feet
height after three bounces:
feet

(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.)
