Using the data from Data Set IX in Appendix B, divide the United States into four regions, as follows:

Northeast CT ME MA NH NJ NY PA RI VT
Midwest IL IN IA KS MI MN MD MS NE ND OH SD WI
South AL AR DE DC FL GA KY LA MD NC OK
SC TN TX VA WV
West AK AZ CA CO HI ID MT NV NM OR UT
WA WY
Find the total population for each region, and draw a Pareto chart and a pie graph for the data. Analyze the results. Explain which chart might be a better representation for the data.
