11.8. Referto the previous exercise. Using software with the "Florida crime" data file at the text website:

(a) Construct box plots for each variable and scatterplots and partial regression plots between y and each ofx\ and X2. Interpret these plots.

(b) Find the prediction equationsforthe (i) bivariate effects of xi and of X2, (ii) multiple regression model. Interpret.

(c) Find R 2

for the multiple regression model, and show that it is not much larger than r 2

for the model using urbanization alone as the predictor. Interpret.
