Suppose That the Sample Regression Line of a First-Order Model $= 4 + 3 x _ { 1 } + 2 x _ { 2 }$

question 13

True/False

Suppose that the sample regression line of a first-order model is $= 4 + 3 x _ { 1 } + 2 x _ { 2 }$ . If we examine the relationship between y and $x _ { 1 }$ for three different values of $x _ { 2 }$ , we observe that the effect of $x _ { 1 }$ on $y$ remains the same no matter what the value of $x _ { 2 }$ .
