Question: The question is, is it the shoes? In order to determine if a certain brand of jogging shoes (Joguars) is better for speed, a random sample of eight joggers is selected. The joggers are asked to jog a mile in Joguars and a mile in another brand. The runners were randomly assigned to run in Joguars first or in Brand X first, with the runs separated by a day. Do the times recorded indicate that Joguars allow for better jogging times? Here are the mile times, in minutes. Ask SPSS to do this one for you.
