The machines are made to order, so the production rate varies from month to month. Before shipping, each machine is subject to extensive testing. Based on the tests the machine is either passed or sent back for rework. During the past 20 months the firm has had to rework the following numbers of machines: (given) Consider the example of Applied Machines presented above. Based on the estimate of the probability that a machine is sent back for rework computed from the 20 months of data, determine the following:a. If the company produces 35 machines in one particular month, how many, on average, require rework?b. Out of 100 machines produced, what is the probability that more than 20 percent of them require rework?

Recall that the normal probability table gives area under the curve to the left of a given z value. Since we want the area to the right of z = 3.90 and the area under the entire curve is 1, the area to the left of z = 3.90 can be subtracted from 1. Use the table to find the probability that a student who has done their homework and attended lectures will obtain a grade of A on this test, P(z ≥ 3.90), rounding the result to four decimal places. P(z ≥ 3.90) = 1 − P(z ≤ 3.90) = 1 − =arrow_forward
