14.4 SOC In problem 13.5, crime and population data were presented for each of 10 cities. The data are reproduced here.

Take the three crime variables as the dependent variables (one at a time) and

a. Find the multiple regression equations

(unstandardized) with growth and urbanization as independent variables.

b. Make a prediction for each crime variable for a city with a 5% growth rate and a population that is 90% urbanized.

c. Compute beta-weights for each independent variable in each equation and compare their relative effect on each dependent.

d. Compute R and R 2 for each crime variable, using the population variables as independent variables.

e. Write a paragraph summarizing your findings.
