Based on past experience a telemarketing firm has found, Ask an Expert

Statistics

Based on past experience, a telemarketing firm has found that calls to prospective customers take an average of 2.0 minutes, with a standard deviation of 1.5 minutes. The distribution is positively skewed, since persons who actually become customers require more of the caller's time than those who are not home, who simply hang up, or who say they're not interested. Albert has been given a quota of 220 calls for tomorrow, and he works an 8-hour day. Assuming that his list represents a simple random sample of those persons who could be called, what is the probability that Albert will meet or exceed his quota?
