There are two tanks at the aquarium, tank a and tank b. Each tank has two section. The volume of one section of tank a is 24 cubic feet. The volume of the other section of tank a is 96 cubic feet. What is the volume, in cubic feet, of tank a?

(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.)
