The College Avenue Sub Shop is located in a small college town. Virtually all of its phone delivery orders are in the evening, between 5:00 P.M. and 1:00 A.M., so the shop has a delivery person for that time period. It receives an average of about 3 orders per hour (Poisson distributed). However, because of the different distances the delivery person must travel, the service time is undefined, with a mean of 15 minutes and a standard deviation of 6 minutes. Compute L, Lq, W, and Wq.
