A multiple regression model has the form: $\hat { y } = 5.25 + 2 x _ { 1 } + 6 x _ { 2 }$ . 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\hat { y } = 5.25 + 2 x _ { 1 } + 6 x _ { 2 }y^​=5.25+2x1​+6x2​
