Susan Sherer’s grocery store has noted the following figures with regard to the number of people who arrive at the store’s three checkout stands and the time it takes to check them out:
Arrivals/Minute Frequency
0 .............. .3
1 .............. .5
2 .............. .2
Service Time (minute) Frequency
1 .............. .1
2 .............. .3
3 .............. .4

Simulate the utilization of the three checkout stands over 5 minutes, using the following random numbers: 07, 60, 77, 49, 76, 95, 51, 16, and 14. Record the results at the end of the 5-minute period. Start at time = 0.
