An automotive researcher wanted to estimate the difference in distance required to come to a complete stop while traveling 40 miles per hour on wet versus dry pavement. Because car type plays a role, the researcher used eight different cars with the same driver and the same tires. The braking distance (in feet) on both wet and dry pavement is shown in the table. Test to determine whether it takes longer to brake on wet pavement than dry. Car number 1 2 3 4 5 6 7 8 Wet braking distance 106.9 100.9 108.8 111.8 105.0 105.6 110.6 107.9 Dry braking distance 71.8 68.8 74.1 73.4 75.9 75.2 75.7 81.0
