A multiple regression model has the form: $\tilde { y } = 5.25 + 2 x _ { 1 } + 6 x _ { 2 }$ .As x₂ increases by one unit,holding x₁ constant,then the value of y will increase by: A) 7.25 units B) 6 units on average C) 2 units D) None of these choices

Question

Quizplus · Accepted Answer

The coefficient of $x_2$ in the regression equation is 6, indicating that for each one-unit increase in $x_2$, holding $x_1$ constant, $y$ increases by 6 units on average.

A Multiple Regression Model Has the Form y~=5.25+2x1+6x2\tilde { y } = 5.25 + 2 x _ { 1 } + 6 x _ { 2 }y~​=5.25+2x1​+6x2​
