A mail order supplier advertises same-day service on every order. Recently, the movement of orders has not gone as planned. The director of customer service has completely redone the method of order handling. The goal of a mail order supplier is to have fewer than 5 unfilled orders on hand at the end of 95% of the working days. Frequent checks of the unfilled orders follow a Poisson Distribution (discrete frequency distribution) with a mean of 2 orders.
