In a double sampling plan, N=5000, n1=100, c1=0 and n2=100, c2=1.

a. Compute the probability of acceptance of 1% non conformance lot

b. Assume that a lot rejected by this sampling plan will be 100% inspected, what will be thee AOQ if the submitted product is 1% non conforming?

c. Considering both inspection of samples and inspection of rejection lots, what will be the average number of articles inspected per lot, if teh submitted product is 1% non conforming?

d. What single sampling plan should be used for a lot size of 1500 and LTPD of 5% with a consumer risk of 0.10 if the process average is estimated as 06% defective?
