At a convenience store there is only one cashier. It is estimated that average service time by the cashier is 2 minutes, and the standard deviation of service time is 1 minute. The owner observed that on average customers arrive every 4 minutes, and the standard deviation of the time between two consecutive arrivals is also 4 minutes. Answer the following questions (or fill in the blanks): a) E(A) = ________, E(S) = _________ (Note: please include the time unit)...
