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

question 45

True/False

Suppose that the sample regression equation of a model is $\tilde { y } = 4 + 1.5 x _ { 1 } + 2 x _ { 2 } - x _ { 1 } x _ { 2 }$ .If we examine the relationship between x₁ and y for four different values of x₂,we observe that the four equations produced differ only in the intercept term.
