1. Plot distributions (histograms) of each of these four variables, using either:
a. Engineering paper, manually preparing these plots

b. Excel which can prepare these distributions for you

2. Ensure you identify the mean value on each plot and also determine the following statistics to demonstrate the variation of queuing performance:

a. For each variable, calculate the probability that the data will exceed 125, 150, 175 and 200% of the mean

b. Determine each increment until the statistic reaches near zero

c. Again you can do these calculations manually or by Excel

Note: Make graphs out of the excel sheet provided, and a graph of the interarrival times, the t que, the t ser, and the t sys.
