Suppose That the Sample Regression Equation of a Model Is $= 4 + 1.5 x _ { 1 } + 2 x _ { 2 } - x _ { 1 } x _ { 2 }$

question 65

True/False

Suppose that the sample regression equation of a model is $= 4 + 1.5 x _ { 1 } + 2 x _ { 2 } - x _ { 1 } x _ { 2 }$ . If we examine the relationship between $x _ { 1 }$ and y for four different values of $x _ { 2 }$ , we observe that the four equations produced differ only in the intercept term.
