Suppose That the Sample Regression Equation of a Model Is

Question 9

Multiple Choice

Suppose that the sample regression equation of a model is Suppose that the sample regression equation of a model is = 10 + 2x<sub>1</sub> + 3x<sub>2</sub> - x<sub>1</sub>x<sub>2</sub>.If we examine the relationship between x<sub>1</sub> and y for four different values of x<sub>2</sub>,we observe that the: A) four equations have different coefficients of x<sub>1</sub>. B) four equations produced differ only in the intercept term. C) coefficient of x<sub>2</sub> remains unchanged. D) coefficient of x<sub>1</sub><sub> </sub>remains unchanged. = 10 + 2x1 + 3x2 - x1x2.If we examine the relationship between x1 and y for four different values of x2,we observe that the:


A) four equations have different coefficients of x1.
B) four equations produced differ only in the intercept term.
C) coefficient of x2 remains unchanged.
D) coefficient of x1 remains unchanged.
