Refer to the Florida data file at the text website, shown partly in Table 9.15 for Exercise 9.39, giving countywide data for several variables in Florida. For those data, use software to analyze y = crime rate and x = percentage living in an urban environment.

(a) Construct a box plot for y. Interpret.

(b) Find the prediction equation. Interpret the y-intercept and slope.

(c) Using the slope, find the difference in predicted crime rates between counties that are 100% urban and counties that are 0% urban. Interpret.

(d) Report and interpret the correlation and r2.
