Suppose that AQL = 0.5 percent, a = 5 percent, LTPD = 2 percent, and N = 1, 000.
a. Find the AOQL for the single-sampling plan that best fits the given parameter values.
b. For each of the following experiments, find the AOQL for the best single-sampling plan. Change only the parameter indicated, holding all others at their original values.
i. Change N to 2,000.
ii. Change AQL to 0.8 percent.
iii. Change LTPD to 6 percent.
d. Discuss the effects of changes in the design parameters on plan performance, based on the three experiments in part (b).
