A transportation department tests the braking abilities of various cars. For this experiment, the department measured the stopping distances on dry pavement at 100 kph (kilometers per hour, about 62 mph) of four models: A, B, C, and D. Each car accelerated to 100 kilometers per hour on a test track; then the brakes were applied. The distance required to come to a full stop was measured, in meters. The test was repeated for each car 10 times under identical...
