5.11. It is known that 30% of all customers of a major credit card pay their bills in full before any interest charges are incurred. Suppose a simple random sample of 150 credit card holders is selected. (Note that n p-150 (0.3)-45 > 5, and n(1-p) 150(0.7)-105 > 5, so the normal approximation to the binomial is quite valid.) What is the probability that 30 or fewer customers pay their account balances in full before any interest charges are incurred?...

In an attempt to justify this claim, a randomly selected sample of cable subscribers will be polled on this issue. (a) Suppose that the advocate's claim is true, and suppose that a random sample of 5 cable subscribers is selected. Assuming independence, use an appropriate formula to compute the probability that 3 or more subscribers in the sample are not satisfied with...
