For the following regression equation $\tilde { y } = 10 + 3 x _ { 1 } + 4 x _ { 2 }$ ,a unit increase in x₂ increases the value of y on average by: A) 4 B) 7 C) 17 D) an amount that depends on the value of x₁.

Question

Quizplus · Accepted Answer

The coefficient of $x_2$ in the regression equation is 4, indicating that a unit increase in $x_2$ increases $y$ by 4 on average, holding $x_1$ constant.

For the Following Regression Equation y~=10+3x1+4x2\tilde { y } = 10 + 3 x _ { 1 } + 4 x _ { 2 }y~​=10+3x1​+4x2​

For the Following Regression Equation $\tilde { y } = 10 + 3 x _ { 1 } + 4 x _ { 2 }$
