A domestic manufacturer of watches purchases quartz crystals from a Swiss firm. The crystals are shipped in lots of 1,000. The acceptance sampling procedure uses 20 randomly selected crystals. a. Construct operating characteristic curves for acceptance numbers of 2, 3, and 4 (to 4 decimals). C P=0.02 p = 0.06 p=0.09 p=0.11 P=0.16 2 3 4 b. If po is 0.02 and Pi = C At Po=0.02 2 3 000 000 0.09, what are the producer's and consumer's risks for each sampling plan in part (a) (to 4 decimals)?
