Most liquids when cooled will simply shrink. Water on the other hand, actually expands when it is frozen. Its volume will increase by about 9 percent, Suppose you have one third of a gallon of water that gets frozen. what is the volume of the ice that you now have

(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.)
