A researcher compares two compounds (1 and 2) used in the manufacture of car tires that are designed to reduce braking distances for SUVs equipped with the tires. SUVs equipped with tires using compound 1 have a mean braking distance of 54 54 feet and a standard deviation of 6.7 6.7 feet. SUVs equipped with tires using compound 2 have a mean braking distance of 62 62 feet and a standard deviation of 14.9 14.9 feet. Suppose that a sample of 62 62 braking tests are performed for each compound. Using these results, test the claim that the braking distance for SUVs equipped with tires using compound 1 is shorter than the braking distance when compound 2 is used. Let μ1 μ 1 be the true mean braking distance corresponding to compound 1 and μ2 μ 2 be the true mean braking distance corresponding to compound 2. Use the 0.1 0.1 level of significance.
