Samples of size 50 are drawn from lots of 1,000 items. The lot is rejected if there are more than two defectives in the sample. Using a binomial approximation, graph the OC curve as a function of p, the proportion of defectives in the lot. For an AQL of .01 and an LTPD of .10, find  and .

a. Graph the OC curve and identify the Type 1 and Type 2 error probabilities (that is, develop a graph similar to Figure 12–14).

b. Graph the AOQ curve and identify the value of the AOQL.
