A domestic manufacturer of watches purchases quartz crystals from Swiss firm. The crystals are shipped in lots of 1000. The acceptance sampling procedure uses 20 randomly selected crystals. a. Construct operating characteristic curves for acceptance criteria of 1, 2, and 3 (to 4 decimals). p=0.02 p=0.06 p=0.09 p=0.11 p=0.16 1 2 3 b. If po is 0.02 and P1 = 0.09, what are the producer's and consumer's risks for each sampling plan in part (a) (to 4 decimals)? At po = 0.02 Producer's Risk At P1 = 0.09 Consumer's Risk 1 2 3
