1. For the sampling plan N= 1500, n= 150, c= 3, construct the average outgoing quality curve. What is the AOQL? Interpret it.
2. Construct the ATI curve for the sampling plan N = 1200, n= 50, c =1. Suppose that the process average nonconforming rate is 3%. Explain the value of ATI for that level of nonconformance.
