To compare the dry braking distances from 30 to 0 miles per hour for two makes of​ automobiles, a safety engineer conducts braking tests for 35models of Make A and 35 models of Make B. The mean braking distance for Make A is 41feet. Assume the population standard deviation is 4.6 feet. The mean braking distance for Make B is 45feet. Assume the population standard deviation is 4.3 feet. At alphaequals0.10​,can the engineer support the claim that the mean braking distances are different for the two makes of​ automobiles
