An electronic component for a medical X-ray unit is produced in lots of size N =30. An acceptance testing procedure is used by the purchaser to protect against lots that contain too many nonconforming components. The procedure consists of selecting five components at random from the lot (without replacement) and testing them. If none of the components is nonconforming, the lot is accepted. (d) Suppose that the purchaser will reject the lot with the decision rule of finding one or more nonconforming components in a sample of size n, and wants the lot to be rejected with probability at least 0.95 if the lot contains five or more nonconforming components. How large should the sample size n be?

An electronic component for a medical X-ray unit is produced with an average 5% defective. An acceptance testing procedure consists of selecting 10 components at random from the lot (without replacement) and testing them. If none of the components is nonconforming, the lot is accepted. a) What is the probability of lot acceptance? b) What is the probability of finding more than one non-conforming components in the sample? c) What is the average number of components that must be tested...
1. Many companies use a incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of n components can be viewed as the n trials of a binomial experimem. The outcome for each component tested (trialD will be that the component is classified as good or defective defective components in the lot do not exceed 1 %. Suppose a random sample of fiver...
