Acceptance sampling is employed to monitor the quality of incoming raw materials. Assume a purchaser of electronic components permits 1 percent of the components to be defective. To make sure the quality of incoming parts, a purchaser or manufacturer normally samples 20 parts and allows 1 defect.
(a) Determine the likelihood of accepting a lot that is 1 percent defective? (Round answer to 4 decimal places.)
(b) If the quality of the incoming lot was actually 2 percent defective, what is the likelihood of accepting it? (Round answer to 4 decimal places.)
(c) If the quality of the incoming lot was actually 5 percent defective, what is the likelihood of accepting it? (Round answer to 4 decimal places.)
