A multiple regression model has the form $\hat { y } = \hat { \beta } _ { 0 } + \hat { \beta } _ { 1 } x _ { 1 } + \hat { \beta } _ { 2 } x _ { 2 } .$ The coefficient $\hat { \beta } _ { 2 }$ is interpreted as the change in $y$ per unit change in x2.

The Answer of A multiple regression model has the form $\hat { y } = \hat { \beta } _ { 0 } + \hat { \beta } _ { 1 } x _ { 1 } + \hat { \beta } _ { 2 } x _ { 2 } .$ The coefficient $\hat { \beta } _ { 2 }$ is interpreted as the change in $y$ per unit change in x2.

A Multiple Regression Model Has the Form y^=β^0+β^1x1+β^2x2.\hat { y } = \hat { \beta } _ { 0 } + \hat { \beta } _ { 1 } x _ { 1 } + \hat { \beta } _ { 2 } x _ { 2 } .y^​=β^​0​+β^​1​x1​+β^​2​x2​.
