The following economic model predicts whether a voter will vote for an incumbent school board member INCUMBENT = $\beta$ ₁ + $\beta$ ₂ MALE + $\beta$ ₃PARTY + $\beta$ ₄MARRIED + $\beta$ ₅KIDS
Where
INCUMBENT = 1 if the voter votes for them,0 otherwise.
MALE = 1 if the voter is a male.
PARTY indicates the voter is registered with the same political party as the incumbent.
MARRIED = 1 for married voters,0 otherwise.
KIDS is the number of school age kids living in the voter's house.
If you believe marriage affects male and female voters differently,which variable should you add to the economic model to allow you to test the hypothesis?
