Customers arrive at a checkout counter in a department store according to a Poisson distribution at an average of 7 per hour. If it takes approximately 10 minutes to serve each customer, find the mean and variance of the total service time for customers arriving during a 1-hour period. Assume that a sufficient number of servers are available so that no customer must wait for service. What is the probability that the total service time will exceed 2.5 hours? (Use at least four digits after the decimal if rounding.)
