An instructor who taught two sections of engineering statistics last term, the first with 20 students and the second with 30, decided to assign a term project. after all projects had been turned in, the instructor randomly ordered them before grading. consider the first 15 graded projects. (a) what is the probability that exactly 10 of these are from the second section? (round your answer to four decimal places.) (b) what is the probability that at least 10 of these are from the second section? (round your answer to four decimal places.)

(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.)
