Two processes are used to produce forgings used inan aircraft wing assembly. Of 200 forgings selectedfrom process 1, 10 do not conform to the strengthspecifications, whereas of 300 forgings selected fromprocess 2, 20 are nonconforming.(a) Estimate the fraction nonconforming for eachprocess.(b) Test the hypothesis that the two processeshave identical fractions nonconforming. Use(c) Construct a 90% confidence interval on the differencein fraction nonconforming between thetwo processes
