Exam 10: Extension: Acceptance Sampling

Suppose we have a lot of several thousand units of a finished good. For an acceptance sampling plan with n = 20 and c = 2, what will be the average outgoing quality for lots with 5 percent defectives? 10 percent? 15 percent? 20 percent?

Question 21

A quality inspector for Alpha-Beta Co. is concerned about the quality of the batch of several thousand blank DVD disks which his company produced this week and is preparing to ship. If the cost of replacing a defective DVD disk once it has been shipped is $2.00, while the cost of 100 percent inspection prior to shipment is $.40 each, at what point is he indifferent between 100 percent inspection and shipment without inspection?

Question 23

The quality manager for Graphics, Inc., is concerned about the quality of the lot of several thousand posters which her company printed this week and is now preparing to ship. If she uses an acceptance sampling plan of n = 10 and c = 2, what is the probability that, if this lot is 10 percent defective, it will be accepted for shipment without inspection?

The quality manager for Microelectronics, Inc., is concerned about the quality of the batch of several thousand Z-box games which his company is about to ship. If the cost of replacing a defective Z-box game once it has been shipped is $5.00, while the cost of complete (100 percent) inspection prior to shipment is $.20 each, at what point is he indifferent between complete inspection and shipment without inspection?

Question 27

The quality manager for Microelectronics, Inc., is concerned about the quality of the batch of several thousand Z-box games which his company is about to ship. If, based on his acceptance sample, he decides to ship this batch without inspection, which type error would be possible?

Question 28

A manufacturer purchases large quantities of metal brackets from several suppliers. The brackets are shipped in lots of 8,000 each. Random samples of 40 brackets are taken from each lot, and the lot is rejected if any defectives are discovered. Rejected lots are subjected to 100 percent inspection, and any defectives are replaced with good brackets. Determine the average outgoing quality limit for this sampling plan.

Question 36

A firm uses acceptance sampling to evaluate batches of inputs. Ideally, the defect rate would be no more than 3.5 percent. The firm knows that on occasion, batches with higher defect rates will be accepted. However, if the defect rate reaches 7 percent, the firm would like there to be very little chance of that batch being accepted. This value, 7 percent, is the firm's:
