A college admissions officer proposes to use regression to model a student's college GPA at graduation in terms of the following two variables:

x1 = high school GPA
x2 = SAT score

The admissions officer believes the relationship between college GPA and high school GPA is linear and the relationship between SAT score and college GPA is linear. She also believes that the relationship between college GPA and high school GPA depends on the student's SAT score. She proposes the regression model:

E(y) = β0 + β1x1 + β2x2 + β3x1x2

Explain how to determine if the relationship between college GPA and SAT score depends on the high school GPA.
