Question

An automotive researcher wanted to estimate the difference in the 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 tires. The braking distance (in feet) on both wet and dry pavement is shown in the table. Construct a 95% confidence interval for the mean difference in braking distance on wet versus dry pavement where the differences are computed as “wet minus dry”. Interpret the interval.
