In the lunchtime rush example, the arrival rate changed fairly gradually throughout the period of interest Assume now that the arrival rate first increases and then decreases in a more abrupt manner. Specifically, replace the arrival rates in the example by the following: 15, 20, 70, 85, 30, and 20. Note that the sum of these rates is the same as the sum of the rates in the example, so that we expect the same total number of arrivals, but now they are more concentrated in the noon to 1 P.M. hour. Compare the results with these arrival rates to the results in the example. Write a short report on your findings.
