For the Florida data file (below) giving countywide data in Florida for several variables, a moderate positive correlation (r = 0.47) exists between crime rate and percent who are high school graduates. The percentage living in urban areas is also strongly correlated with crime rate (r = 0.68) and with high school graduation rate (r = 0.79). a. Explain why the association between crime rate and high school graduation rate could disappear, or even change direction, when we control for...
