Scatterplots. In Exercises 5–8, use the given paired data from Appendix B to construct a scatterplot.
President's Heights Refer to Data Set 12 in Appendix B, and use the heights of U.S. presidents and the heights of their main opponents in the election campaign. Does there appear to be a correlation?
Answer :
Step 1 of 1 :
The heights of U.S. presidents and the heights of their main opponents in the election campaign.
The data is given below.

Now we have to draw a scatter plot.
Then the scatter plot is given below.
Because the points are scattered throughout with no obvious pattern, there does not appear to be a correlation.
