Sue, a consumer analyst, asks participants to rate the comfort of the ride for two brands of all-terrain tires: Road Hug and Path Elite. Road Hug is rated more comfortable, with a mean of 5.5, than Path Elite, which is found to have a mean of 4.3. The Type I error would be to conclude that Road Hug is more comfortable than Mud Handler when a true difference in comfort exists. a. no more comfortable than Mud Handler when Trail Cushion is actually more comfortable.
b. no more comfortable than Mud Handler when no difference in comfort exists.
c. more comfortable than Mud Handler when the two tires are equally comfortable.
