Refer to Example 6 and the Buchanan and the Butterfly Ballot data file on the text CD. Let y = Buchanan vote and x = Gore vote.
a. Construct a box plot for each variable. Summarize what you learn.
b. Construct a scatterplot. Identify any unusual points. What can you learn from a scatterplot that you cannot learn from box plots?
c. For the county represented by the most outlying observation, about how many votes would you have expected Buchanan to get if the point followed the same pattern as the rest of the data?
d. Repeat parts a and b using y = Buchanan vote and x = Bush vote.
