1. Two processes A and B are used to produce forgings in aireraft wing assembly. Of
200 forgings selected from process A, 10 do not conform to the strength specifications.
Whereas, of 300 forgings selected from process B, 30 do not conform to the strength
specifications.
i. Construct a 95% confidence interval an the difference in fraction conforming strength
specifications between the two processes.
ii. Based on the results in part (i), is there any indication that the two processes have
identical fractions of conforming strength specifications? Justify your answer.
