Most car-rental companies keep their cars for about a year and then sell them to used car dealerships. Suppose one company decided to sell the used cars themselves. Because most used car buyers make their decision on what to buy and how much to spend based on the car’s odometer reading, this would be an important issue for the car-rental company. To develop information about the mileage shown on the company’s rental cars, the general manager took a random sample of 658 customers and recorded the average number of miles driven per day. Use a graphical technique to display these data.
