Exam 22: Acceptance Sampling Plans

This OC curve represents a sampling plan developed for a lot size of 1000,a sample size of 15,and an acceptance number of 2.The probability of acceptance for each of the first six points appears next to the plotted point.What incoming fraction defective is associated with the average outgoing quality limit? $This OC curve represents a sampling plan developed for a lot size of 1000,a sample size of 15,and an acceptance number of 2.The probability of acceptance for each of the first six points appears next to the plotted point.What incoming fraction defective is associated with the average outgoing quality limit?$
