Draw the primary and supplementary OC curves for a double-sampling plan with n1 = 50, c1 = 2, n2 = 100, and c2 = 6. If the incoming lots have fraction nonconforming p = 0.05, what is the probability of acceptance on the first sample? What is the probability of final acceptance? Calculate the probability of rejection on the first sample.
Answer to relevant QuestionsSuppose that during the analyze phase an obvious solution is discovered. Should that solution be immediately implemented and the remaining steps of DMAIC abandoned? Discuss your answer. (a) Derive an item-by-item sequential-sampling plan for which p1 = 0.01, a = 0.05, p2 = 0.10, and β= 0.10. (b) Draw the OC curve for this plan. A product is supplied in lots of size N = 10,000. The AQL has been specified at 0.10%. Find the normal, tightened, and reduced single-sampling plans from MIL STD 105E, assuming general inspection level II. Draw the type-B OC curve for the single-sampling plan n = 50, c = 1. A ChSP-1 plan has n = 4, c = 0, and i = 3. Draw the OC curve for this plan.
