a number cube is rolled many times with the results shown in the table below.

number rolled
1 2 3 4 5 6

number of rolls
13 12 12 14 11 18

the theoretical and experiment probabilities for rolling a 2 are [close together, the same, not close together].

(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.)
