The U.S. Postal Service is attempting to reduce the number of complaints made by the public against its workers.  In order to facilitate this task, a staff analyst for the service regresses the number of complaints lodged against an employee last year on the hourly wage of the employee for the year.  The regression equation finds:

Y = 20.2 - 1.2X with a r2 of .73

What does r2 of .73 tell us? Is this a strong or weak correlation?  How can you tell?
