A large textbook publishing company hired nine new sales representatives 3 years ago. At the time of hire, the nine were ranked according to their potential.

Now 3 years later the company president wants to know how well their potential ranks correlate with their sales totals for the 3 years. [PT14-13]

Is there significant correlation at the 0.05 level?
