If wages were increased by 1.00 what is the expected effect, Ask an Expert

Statistics

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

A. What is the IV? What is the DV?

B. If wages were increased by $1.00, what is the expected effect on the number of complaints received per employee? How can you tell?
