29. The average major league fastball is 92.0 miles per hour (mph), and the speeds are

suspiciously normally distributed. The other day a scout recorded the velocity of a random

sample of 14 fastballs that I threw. Does the evidence imply that my pitches are better than the

average major league pitcher in regards to velocity? Use the a = .05 level of significance.

Assume that I suffer no loss in stamina and thus my pitch speeds are unaffected by each other.
