In quality control technique, acceptance sampling is used to monitor incoming shipment of parts, raw materials, and so on. In the electronic industry, components parts are commonly shipped from suppliers in large lots. Reynolds Electronics accepts a lot from a particular supplier if the defective components in the lot do not exceed 2%. Suppose a random of 5 items from a recent shipment is tested.

1. What is the appropriate distribution that can be used here? Explain why.

2. What is the probability of no items are defective?
3. What is the probability of exactly one item defective?
4. What is the probability of having at least one defective?

5. What is the probability of having a majority of items defective?
6. Would you feel comfortable accepting a lot with one defective item? Justify your answer.

As the quality engineer, you monitor supplier shipments for quality before accepting the shipment. Historically, this supplier has produced about one defective item out of 60. When a new shipment comes, you take a sample of size 5 items from the shipment, and if there is more than one defective item, you reject the shipment. What is the probability of accepting a shipment? Your answer can be rounded to three decimal digit accuracy when entered. Probability is =

2. Nova Ceramics manufacture specialty ceramic parts for non-metallic applications. Parts must be precision drilled such that when assembled with other parts they are a perfect fit. Inspecting parts is time consuming so the practice is for customers to inspect a sample of items from a shipment and if no more than 1 item is defective, the shipment is accepted. a) Suppose that the on average 0.1% of units are defective. The customer makes the decision on acceptance based upon...

Suppose that a supplier ships components in lots of size 5000. A single-sampling plan with n = 50 and c = 2 is being used for receiving inspection. Rejected lots are screened, and all defective items are reworked and returned to the lot. (a) Draw the OC curve for this plan. (b) Find the level of lot quality that will be rejected 90% of the time. (c) Management has objected to the use of the above sampling procedure and wants...

KALI, Inc., manufactures home appliances that are marketed under a variety of trade names. However, KALI does not manufacture every component used in its products. Several components are purchased directly from suppliers. For example, one of the components that KALI purchases for use in home air conditioners is an overload protector, a device that turns off the compressor if it overheats. The compressor can be seriously damaged if the overload protector does not function properly, and therefore KALI is concerned...
