Tire Stopping Distances

Description

The data frame Tire has the stopping distances measured to the nearest foot for a standard sized car to come to a complete stop from a speed of sixty miles per hour. There are six measurements of the stopping distance for four different tread patterns labeled A, B, C, and D. The same driver and car were used for all twenty-four measurements. Data are used in Example 11.1 and 11.2.
