To verify a proposed service time process generator, you use a stopwatch to time 30 transactions.
a. Using Excel and bin sizes of 5 and 15, plot histograms from the data shown below. Qualitatively using these plots, does the uniform process generator (10,55) accurately reflect your observations?
b. What technique would you use to quantitatively assess (or hypothesize) whether this data behaves as a uniform distribution varying from 10 to 55?
