An auto dealer would like to determine if there is a difference in the braking distance (the number of feet required to go from 60mph

to 0mph) of two different models of a high-end sedan. Six drivers are randomly selected and asked to drive both models and brake once they have reached exactly 60mph. The distance required to come to a complete halt is then measured in feet. The results of the test are as follows. Can the auto dealer conclude that there is a significant difference in the braking distances of the two models? Use α=0.10. Let the braking distances of Model A represent Population 1 and the braking distances of Model B represent Population 2.
