The Regression Equation · Exercise 13

The table below represents the relationship between SAT scores on the math portion of the test and high school grade point averages (GPAs).
Use the median–-median line approach to find the equation for the line of best fit.

$$\begin{array}{cc}\text{x (SAT math scores)}& \text{y (GPAs)}\\ \text{624}& \text{90}\\ \text{544}& \text{86}\\ \text{363}& \text{70}\\ \text{373}& \text{71}\\ \text{350}& \text{65}\\ \text{741}& \text{98}\\ \text{262}& \text{60}\\ \text{587}& \text{87}\\ \text{327}& \text{62}\\ \text{364}& \text{67}\\ \text{261}& \text{50}\end{array}$$
