- 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
- 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 that I sent you, I need a graph of the interarrival times, the t que, the t ser, and the t sys.
