A certain grocery store has created the following tables of intervals of random numbers with regard to the number of people who arrive at its three checkout stands ready to check out, and the time it takes to check out the individuals

Simulate the utilization rate of the three checkout stands over four minutes using the following random numbers for arrivals: 07, 60, 49, and 95. Use the following random numbers for service: 77, 76, 51, and 16. Describe the results at the end of the four-minute period.

Arrivals Interval of

Random #s
0 01-30 1 01-10
1 31-80 2 11-40
2 81-00 3 41-80
4 81-00

Indicate whether the statement is true or false

t = RN = Arrival # RN = Service Time =
0 07 0 01-10
1 60 1 77 11-40
2 49 1 76 41-80
3 95 2 51 81-00
16

Note: The first customer arrives at minute 1 and exits at minute 4; the second customer enters at minute 2 and exits at minute 5. A third and fourth customer enter at minute 3. There is one server open, so customer four will wait for one minute until minute 4 when the first customer exits.
