Question: A friend in a political science course asks for your help. She just read that the correlation between the percent of eligible citizens in a city who register to vote and the percent of registered voters in the city who really do vote is .88. She read further that the correlation is significant (p < 0.01).

a. Explain to your friend in plain language what r=0.88 means.

b. Then explain what it means to say that this correlation is statistically significant (P < 0.01). Use plain language- no technical terms.

c. Now explain to your friend what the fact that = 0.77 says about predicting voter turnout from registration data.
