Statistic problem: Hypothesis Testing of running shoes

Directions: Test the following hypotheses using the Traditional Method.  You must show all the steps involved and the final statement must be phrased appropriately for the problem.

A sports-shoe manufacturer claims that joggers who wear its brand of shoe will jog faster than those who don't.  A sample of eight joggers is taken, and they agree to test the claim on a 1-mile track.  The rates (in minutes) of the joggers while wearing the manufacturer's shoe and while wearing any other brand of shoe are shown here.  Test the claim at a 2.5% level of significance.
