4 Refer to Example 11 1. Using computer software for the data in Problem 9.24 for those three variables

a) Construct box plots for cach variable and scatter diagrams and partial regression plots between Y and each of X, and X? If available with your software, also construct coplots Interpret these plots.

b) Find prediction equations for the bivanate models, using education to predict crime rate and using urbanization to predict come rate. Interpret.

c) Construct the correlation matrix for these three variables Interpret

d) Find the prediction equation for the multiple regression model Interpret

e) Find R for the niultiple regression model, and show that it is not much larger than r for the model using urbanization alone as the predictor Interpret
