Problem:
The time between arrivals at the drive-through window of Barry Harmon's fast-food restaurant follows the distribution given in the table. The service-time distribution is also given. Use the random numbers provided to simulate the activity of the first 4 arrivals. Assume that the window opens at 11:00 a.m. and that the first arrival occurs afterward, based on the first inter-arrival time generated.
