Part 1: The EXCEL worksheet below contains a simulation of the amount of time customers spend at a busy gas station. The time between arrivals of cars at one of the pumps is assumed to be uniformly distributed with a minimum of 4 minutes and maximum of 8. The time spent to pump fuel and pay once a car reaches the front of the queue follows a normal distribution with a mean of 5 minutes and a standard deviation of 1.5 minutes. The simulation of 50 cars arriving, lining up, waiting, fueling, and then leaving the station is in rows 12 through 61 of the spreadsheet (rows 15 through 58 are hidden to save space).
