Pelicans have a long flat bill and expandable pouch, and use a spectacular dive-bomb-type plunge into the water to capture fish. A random sample of pelicans at Tigertail Beach on Marco Island was obtained. The height of a plunge was measured (in feet) for each bird, and the data are given in the following table.

A random sample of Georgia drivers renewing their vehicle registration was obtained. Using motor vehicle records, the number of miles driven in the past year was recorded for each. The data (in thousands of miles) were classified by whether the driver had an organ donor card and are given in the following table.
