Ravi wants to paint the ceiling of his restaurant. The ceiling is in the shape of a square. Its side lengths are 52 feet. Suppose each can of paint will cover 208 square feet. How many cans will he need to paint the ceiling?

(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.)
