A MINITAB printout is provided from fitting the multiple regression model to U.S. crime data for the 50 states (excluding Washington, D.C.), on y = violent crime rate, x1 = poverty rate, and
x2 = percent living in urban areas.
a. Predict the violent crime rate for Massachusetts, which has a violent crime rate = 476, poverty rate = 10.2% and urbanization = 92.1% Find the residual, and interpret.
b) Interpret the effects of the predictors by showing the prediction equation relating y and x1 for states with
(i) x2 = 0 and
(ii) x2 = 100. Interpret.
Regression of violent crime rate on poverty rate and urbanization
