An elections officer wants to model voter turnout (y)in a precinct as a function of type of election, national or state. Write a model for mean voter turnout, $E ( y )$, as a function of type of election.
A) $E ( y ) = \beta _ { 0 } + \beta _ { 1 } x _ { 1 } + \beta _ { 2 } x _ { 2 }$, where $x _ { 1 } = 1$ if national, 0 if not and $x _ { 2 } = 1$ if state, 0 if not
B) $E ( y ) = \beta _ { 0 } + \beta _ { 1 } x + \beta _ { 2 } x ^ { 2 }$, where $x =$ voter turnout
C) $E ( y ) = \beta _ { 0 } + \beta _ { 1 } x$, where $x =$ voter turnout
D) $E ( y ) = \beta _ { 0 } + \beta _ { 1 } x$, where $\mathrm { x } = 1$ if national, 0 if state
