Of 40 bank accounts at a small bank, 28 accounts have values of less than $1,000 and the rest have values of at least $1,000. Suppose 5 accounts are randomly sampled (See exercise 9 on page 184 of your textbook for a similar problem.) Question What is the probability that exactly 4 of the 5 accounts have values of at least $1,000? ABC Manufacturing has a policy that it will reject a shipment of parts from its supplier if inspectors find any defective parts in a random sample of 6 parts from the shipment. The supplier has been in business many years and has a long-term defective rate for parts of 5.6%. Question 2 What is the probability that a shipment will be rejected after a given sample of parts is checked?
