A bag contains 42 cups of dog food. Your dog eats 2 1/3 cups of dog food each day. How many days will the dog food last if you feed him the same
amount each day?*
3/8 , 9/16 , 1/4 , or 6/24

(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.)
