Why does voter turnout vary from election to election? For municipal elections in five different cities, information has been gathered on the percentage of registered voters who actually voted, unemployment rate, average years of education for the city, and the percentage of all political ads that used " negative campaigning" (personal attacks, negative portrayals of the opponent's record, etc.). You focus on unemployment as a predictor of voter turnout, finding a slope of 3.00 and a Y intercept of 39. Select the regression equation that describes the relationship between these two variables. OY =-39X+3 O Y = 3X+39 O Y = 39X+3 O 3Y = X +39 O Y = 39 - 3X
