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?
