... It’s not a perfect fit and the 5th and 10th sample percentiles rising above the line is indicative of heavier tales than a normal population, but there is no clear violation of the normality assumption. Also, note that the 5th, 10th, 25 percentiles are closer to the median than are the 75th, 90th an ...

... the same, no matter what the distance is. Of course this is silly. Say distance = 10 miles. Then the mean commute time will probably be around 20 minutes. Say distance = 1 mile. Then the mean commute time will probably be around 5 minutes. So draw two pdfs, one with mean around 20 minutes, the other ...
