In the following example, we’ll examine whether the number of college football wins last season predicts the number of college football wins for the coming season. The research hypothesis is that last season’s wins do predict next season’s, and a one-tail or directional hypothesis is tested at the.05 level of significance.

The data, which are shown below, consist of the wins for 10 teams last season (the X variable) and those for this season (the Y variable).

We’ll deal here only with testing this hypothesis ...
