Asample of size 100 selected from one population has 60 successes, and a sample of size 150 selected from a second population has 95 successes. the test statistic for testing the equality of the population proportions equal (specify your answer to the 4th decimal.)

One integer is 8 times another. if the product is 72, then find the integers

(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.)
