Customers arrive at an ATM machine according to a Poisson process with rate A = 60/h. The following transaction times are observed (in seconds): 28, 71, 70, 70, 51, 62, 36, 25, 35, 87, 69, 27, 56, 25, 36. Estimate the average number of people waiting in line at the ATM. The bank wishes to keep the average line length (number in queue) less than or equal to one. What is the average transaction time needed to achieve this goal (assuming the variance of the transaction times is held constant)?
