Problem 18 in Chapter 15 (p. 526) presented data showing the number of crimes, the amount spend on crime prevention, and the population for a set n = 12 cities. At that time, we used a partial correlation to evaluate the relationship between the amount spent on crime prevention and the number of crimes crime while controlling population. It is possible to use multiple regression to accomplish essentially the same purpose. The data are as follows:

Number of Crimes Amount for Prevention Population Size 3 6 1 4

a. Find the multiple regression equation for predicting the number of crimes using the amount spent on prevention and population as the two predictor variables.

b. Find the value of R2 for the regression equation.

Number of Crimes Amount for Prevention Population Size 3 6 1 4 7 1 6 3 1 7 4 8 11 2 9 12 2 11 8 12 9 13 16 14 17 16 13 17 14 333323
