To compare the braking distances for two types of tires, a safety engineer conducts 35 braking tests for each type. The mean braking distance for Type A is 42 feet. Assume the population standard deviation is 4.7 feet. The mean braking distance for Type B is 45 feet. Assume the population standard deviation is 4.3 feet. At a = 0.10, can the engineer support the claim that the mean braking distances are different for the two types of tires?

To compare the braking distances for two types of tires, a safety engineer
conducts 35 braking tests for each type. The mean braking distance for Type A is
42 feet. Assume the population standard deviation is 4.7 feet. The mean braking
distance for Type B is 45 feet. Assume the population standard deviation is 4.3
feet. At a = 0.10, can the engineer support the claim that the mean braking
distances are different for the two types of tires?
