Consider the outpatient service times in Exercise 3.3. Construct a normal probability plot, an exponential probability plot, and a Weibull probability plot for these data. Do any of these distributions seem to be a reasonable probability model for the data? Based on the plots, which distribution is the best one to describe the outpatient service time?
