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?...
