Here€™s a multiple regression model for the variables considered in Exercise 11.

a) Write the regression model.
b) What does the coefficient of Police Officer Wage mean in the context of this regression model?
c) In a state in which the average police officer wage is $20/hour and the high school graduation rate is 70%, what does this model estimate the violent crime rate would be?
d) Is this likely to be a good prediction? Why do you think that?
