Question: Draw the primary and supplementary OC curves for a double sampling
Draw the primary and supplementary OC curves for a double-sampling plan with . If the incoming lots have fraction nonconforming , 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 Questionsa. Derive an item-by-item sequential-sampling plan for which p1 = 0.01, α = 0.05, p2 = 0.10 and β = 0.10. a. Draw the OC curve for this plan. A product is supplied in lots of size . 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. In exercise An inspector wants to use a variables sampling plan with an AQL of 1.5%. Lots are of size 7,000 and the standard deviation is unknown. Find a sampling plan using Procedure 1 from MIL STD 414. Suppose that a manufacturing process operates in continuous production, such that continuous sampling plans could be applied. Determine three different CSP-1 sampling plans that could be used for an AOQL of 0.198%. a. Verify that the design generators used were I=ACE and I = BDE. b. Write down the complete defining relation and the aliases from this design. c. Estimate the main effects.
