A safety engineer wants to test the braking distances for two types of tires. They conduct 35 braking tests for each type of tire. The mean braking distance for Type 1 is 42 feet. The population standard deviation for Type 1 is 4.7 feet. The mean braking distance for Type 2 is 45 feet. The population standard deviation for Type 2 is 4.3 feet. At the 0.01 level of significance, can the safety engineer support the claim that the mean braking distances are different for the two types of tires? Select the correct answer below: O At the 0.01 level of significance there is enough evidence to support the safety engineer's claim that the mean braking distances are different. O At the 0.01 level of significance there is not enough evidence to support the safety engineer's claim that the mean braking distances are different
