An Elections Officer Wants to Model Voter Turnout (Y)in a Precinct

Multiple Choice

An elections officer wants to model voter turnout (y) in a precinct as a function of the type of precinct. Consider the model relating mean voter turnout, $E ( y )$ , to precinct type:


The $p$ -value for the test $H _ { 0 } : \beta _ { 1 } = \beta _ { 2 } = 0$ is .14. Interpret the result.

A) Reject $H _ { 0 }$ at $\alpha = .10$ ; the model is useful for predicting voter turnout.
B) Reject the model since it only explains $14 \%$ of the variation.
C) Do not reject $H _ { 0 }$ at $\alpha = .10$ ; there is no evidence of a difference between the mean voter turnouts for urban, suburban, and rural precincts.
D) Reject $H _ { 0 }$ at $\alpha = .01$ ; there is evidence of a difference between the mean voter turnouts for urban, suburban, and rural precincts.
