**Homework 3 (I need specific solution to this question, have no clue how to do it)**

Decision Models

1. Consider a single queue single server system. ** Manually,** simulate the customer arrival, service times, and customer departure for the first seven customers of the day. Assume that the number of customers arriving to the system follow a Poisson distribution with a mean of 2 mins. Please assume the following random numbers to calculate the interarrival times:

0.45 0.8 0.71 0.33 0.5 0.62 0.48

In addition, assume that the service time is fixed in 3 mins. Calculate the following statistics:

a) Average waiting time

b) Maximum waiting time

c) Server utilization
