Question: Consider the call handling times in Exercise 3.4. Construct a normal probability plot, an exponential probability plot, and a gamma probability plot for these data.

Consider the call handling times in Exercise 3.4. Construct a normal probability plot, an exponential probability plot, and a gamma 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 is the best one to describe the call handling time?
