3. You will now use linear regression to investigate the claim that some votes cast for Buchanan using the "butterfly ballot" were really intended for Gore. The logic is this: if we can make a regression model to predict how many votes Buchanan would have gotten in Palm Beach county, we can compare this prediction to the number he actually got, and see how much they differ. Use Fit Y by X to estimate a simple linear regression model in which total number of votes cast is the predictor variable and number of votes cast for Buchanan is the response.
