A shipment of 50,000 transistors arrives at a manufacturer plant. The quality control engineer at the plant obtains a random sample of 500 transistors and will reject the entire shipment if 10 or more of the resistors are defective. Suppose that 4% of the resistors in the whole shipment are defective.
- Describe the sampling distribution of the sample proportion of defective resistors, Justify your answer.
- What is the probability the engineer accepts the shipment? Do you believe the acceptance policy is sound? Justify.

7.30 A quality-control inspector rejects any shipment of printed circuit boards whenever 3 or more defectives are found in a sample of 100 boards tested. Find the (1) expected number defective and (2) the probability of rejecting the shipment when the proportion of defectives in the entire shipment is (a) Proportion of Defectives-0.01 Expected Number Defective- Probability of Rejecting the Shipment (b) Proportion of Defectives-0.05 Expected Number Defective- Probability of Rejecting the Shipment- (c) Proportion of Defectives 0.1 Expected Number...

A quality engineer takes 40 subgroups of 100 transistors each from the output of an assembly line. Each transistor is tested and the number of defectives in each sample is recorded. The average proportion (fraction) defective is .0255. The lower and upper control limits for the p chart are a. 0 and 0.100 b. 0.010 and 0.0413 c. 0 and 0.057 d. 0 and 0.0728 e. 0.001 and 0.050

Many companies use a quality control technique called acceptance sampling to monitor 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 40 components can be viewed as the 40 trials of a binomial experiment. The outcome for each component tested (trial) will be that the component is classified as good or defective. Reynolds Electronics accepts a lot from a particular supplier...

A quality control engineer inspects a random sample of 30 calculators from an incoming batch of size 150 and accepts the lot if at most 4 are not in working condition; otherwise the entire lot must be inspected with the cost charged to the vendor. Suppose the lot contains 5 defective calculators. a.) What is the probability that such a lot will be accepted without further inspection? b.) Given the third calculator tested is the first calculator to be defective,...

4. Susan is in charge of quality control at a small fruit juice bottling plant. Each bottle produced is supposed to contain exactly 12 fluid Ounces (fl oz) of juice. Susan decides to test this by randomly sampling 30 filled bottles and carefully measuring the amount of juice inside each. She will recalibrate the machinery if the average amount of juice per bottle differs from 12 fl oz at the 1% significance level. The sample of 30 bottles has an...
