A researcher at a large company has collected data on both the beginning salary and the current salary of 48 randomly selected e
mployees. The least‑squares regression equation for predicting their current salary from their beginning salary is ^ y = − 2532.7 + 2.12 x y^=−2532.7+2.12x . Kathy Jones started working for the company earning $19,000. She currently earns $40,000. What is the residual for Ms. Jones?
I believe it should be B.156 square feet because in order to find the area of a square, you gotta multiply 13ft and 12ft. Once that is solved your answer should be 156.
