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.

The type I error is known as the false positive error. It occurs when the researcher or the experimenter rejects the true null hypothesis incorrectly. The alpha level is represented by the probability of occurring a type I error. It is the p value and below p value we reject the null hypothesis.

The true null hypothesis is there in no difference in comfort.
