This exercise is based on book examples $10-1$ and $10-2.$

$($a$)$ Step $1$: For book example $10-1$ we discussed in class, run the simulation for $10$ hours.

Save the arrival time in an ascii file, "arrivaldata.txt$".$

Step $2$: Run book example $10-2$ using "arrivaldata.txt$"$ as input data for arrivals.

Step $3$: Compare the average waiting time in the system from the two output reports. Are

they the same or not? Explain. $($hint: it has something to do with how random numbers

are generated$).$

$($b$)$ Change the service time distribution in book example $10-1$ and $10-2$ into constant. Repeat

the above three steps.
