When Using the Model $E ( y ) = \beta _ { 0 } + \beta _ { 1 } x$

True/False

When using the model $E ( y ) = \beta _ { 0 } + \beta _ { 1 } x$ for one qualitative independent variable with a $0 - 1$ coding convention, $\beta _ { 1 }$ represents the difference between the mean responses for the level assigned the value 1 and the base level.
