20. Braking Distances- To compare the braking distances for two types of tires a safety engineer conducts 50 braking tests for each of the tow types
of tires. The results of the tests are shown in the figure. At a= 0.10 can the
engineer support the claim that the mean braking distance for Type C is
greater than the mean braking distance for Type D?
