5. When the sixth customer arrives, will the customer get served right away? Simply answer Yes or No.

6. For the six customers simulated above, what is the average waiting time?

7. If the random number generated for the inter arrival time for the 7th customer is 88, then when will the 7th customer arrive?

The manager of a small post office is concerned that the growing township is overloading the one-window service being offered. Sample data are collected on 100 individuals who arrive for service: Frequency Inter arrival time (Time between Arrivals) (minutes) 1 2 3 4 8 35 40 17 Service Time (minutes) 1 2 3 4 Frequency 12 21 41 26 Using the following random number sequence, simulate six arrivals, assume the first arrival time 0. RN for arrivals: 08, 74, 24, 34, 45, 86 RN for service time: 31, 32, 45, 53, 78, 67 (Note: we don't need to use the random number 08 for first arrival, since we assume the first arrival is time 0)
