Chapter 10, Problem 5CQQ

The following exercises are based on the following sample data consisting of numbers of enrolled students (in thousands) and numbers of burglaries for randomly selected large colleges in a recent year (based on data from the New York Times).

5. Predictions The sample data result in a linear correlation coefficient of r = 0.499 and the regression equation $\hat{y}=3.83+2.39x$. What is the best predicted number of burglaries, given an enrollment of 50 (thousand), and how was it found?
