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?
