Exercise 2.134 examined the relationship between region of the country and level of physical activity of the population of US states. From the USStates dataset, examine a different relationship between a categorical variable and a quantitative variable. Select one of each type of variable and use technology to create side-by-side boxplots to examine the relationship between the variables. State which two variables you are using and describe what you see in the boxplots. In addition, use technology to compute comparative summary statistics and compare means and standard deviations for the different groups.

Exercise 2.134

The variables in USStates include the percent of the people in each state who say they have engaged in any physical activity in the last month as well as the region of the country in which the state is found (Midwest, Northeast, South, or West). One of these variables is quantitative and one is categorical, and Figure 2.41 allows us to visualize the relationship between the two variables.
