question 89

Multiple Choice

Suppose that the sample regression line of the first-order model is $\hat { y } = 8 + 2 x _ { 1 } + 3 x _ { 2 }$ .If we examine the relationship between y and x₁ for four different values of x₂,we observe that the:

• A) only difference in the four equations produced is the coefficient of x₂.
• B) effect of x₁ on y remains the same no matter what the value of x₂.
• C) effect of x₁ on y remains the same no matter what the value of x₁.
• D) Cannot answer this question without more information.
