You're interested in whether a relationship exists between the measures of income and affluence and the serious crime rate in US counties. Create two different scatterplots: Median Income vs. Serious Crime Rate and Percent Below Poverty Level vs. Serious Crime Rate. Discuss what the scatterplots tell you about the relationships present in these sets of variables.
