Drivers pay a toll to pass over a busy bridge, and there are many toll booths that collect money. The city manager counted the total number of cars waiting to pay their tolls at 15-minute intervals during two different days, once on a weekday and once on a weekend. The histograms below show the results. The 10–20 interval contains the most observations on both days.
The two distributions for number of cars in line are both skewed right.
The median number of cars for both distributions lies in the 20–30 interval.
There were more than 40 cars in line more often on the weekend than the weekday.
