- Many companies use a quality control technique called acceptable sampling to monitor incoming shipments of parts, raw materials, and so on. In the electronics industry, components 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 1%. Suppose a random sample of five items from a recent shipment is tested.
- Assume that 1 % of the shipment is defective. Compute the probability that no items in the sample are defective.
- Assume that 1 % of the shipment is defective. Compute the probability that exactly one item in the sample is defective.
- What is the probability of observing one or more defective items in the sample if 1% of the shipment is defective?
Homework Answers
Let X be the random variable denoting the number of defective components in a lot of 5 items. X ~ Bin(5, 0.01)
a. The probability that no items in
the sample are defective = P(X = 0) = 
= 0.9510
b. The probability that exactly one
item in the sample is defective = P(X = 1) = 
= 0.0480
c. The probability of observing one or more defective items in the sample = P(X >=1) = 1 - P(X = 0) = 1 - 0.9510 = 0.0490

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...
