Why does voter turnout vary from election to election? For municipal elections in five different cities, information has been gathered on the percentage of eligible 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.). For each relationship:
a. Draw a scattergram and a freehand regression line.
b. Compute the slope (b) and find the Y intercept (a).
c. State the least-squares regression line and predict the voter turnout for a city in which the unemployment rate was 12, a city in which the average years of schooling was 11, and an election in which 90% of the ads were negative.
d. Compute r and r2.
e. Assume these cities are a random sample and conduct a test of significance for each relationship.
f. Describe the strength and direction of the relationships in a sentence or two. Which (if any) relationships were significant? Which factor had the strongest effect on turnout?
