Question 3A machine is set to produce no more than 0.07 defectives when properly adjusted. After the machine had been in operation for some time, asample of one hundred pieces was tested. Twenty defectives pieces were observed. Is there evidence at the 5% level of significance that themachine needs readjustment?(a) State the null and alternative hypotheses for this test.(b) Compute the value of the Test Statistic?(c) State the p-value for this test.(d) State the conclusion for the test. Give reasons for your answer.

Let p be the proportion of defectives produced by the machine. Given that sample size n=100, Number…
