Suppose That the Sample Regression Equation of a Model Is $=4.7+2.2 x_{1}+2.6 x_{2}-x_{1} x_{2}$

True/False

Suppose that the sample regression equation of a model is $=4.7+2.2 x_{1}+2.6 x_{2}-x_{1} x_{2}$ . If we examine the relationship between y and $x _ { 2 }$ for $x _ { 1 }$ = 1, 2 and 3, we observe that the three equations produced not only differ in the intercept term, but the coefficient of $x _ { 2 }$ also varies.
