# Question

We wish to find a single-sampling plan for a situation where lots are shipped from a supplier. The supplier’s process operates at a fallout level of 0.50% defective. We want the AOQL from the inspection activity to be 3%.

(a) Find the appropriate Dodge–Romig plan.

(b) Draw the OC curve and the ATI curve for this plan. How much inspection will be necessary, on the average, if the supplier’s process operates close to the average fallout level?

(c) What is the LTPD protection for this plan?

Suppose 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. Suppose that two fair dice are tossed and the random variable observed—say, x—is the sum of the two up faces. Describe the sample space of this experiment, and determine the probability distribution of x. A supplier ships a product in lots of size N = 8,000. We wish to have an AOQL of 3%, and we are going to use single sampling. We do not know the supplier’s process fallout but suspect that it is at most 1% defective. (a) ...Suppose that a product is shipped in lots of size N = 5,000. The receiving inspection procedure used is single sampling with n = 50 and c = 1. (a) Draw the type-A OC curve for the plan. (b) Draw the type-B OC curve for this ...A chain-sampling plan is used for the inspection of lots of size N = 500. The sample size is n = 6. If the sample contains no defectives, the lot is accepted. If one defective is found, the lot is accepted provided that the ...Post your question
