A company knows from experience that 0.3% of the electronic parts it produces are defective. Use a Poisson distribution to find the probability that a shipment of 990 parts will have at least 3 defective electronic parts.

a.) For this example, the Poisson distribution is a _________(good, excellent) approximation for the binomial distribution. Show why.

b.) The probability is ____________ that this shipment will contain at most 3 defective electronic parts.

A machine produces parts that are either defect free (90%), slightly defective (3%), or obviously defective. Prior to shipment produced parts are passes through an automatic inspection machine, which is supposed to be able to detect any part that is obviously defective and discard it. However, the inspection machine is not perfect. A part is incorrectly identified as defective and discarded 2% of the time that a defect free part is input. Slightly defective parts are marked defective and discarded...

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...

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...
