Education: Violent Crime The following data are based on information from the book Life in America’s Small Cities (by G. S. Thomas, Prometheus Books).

Let x be the percentage of 16- to 19-year-olds not in school and not high school graduates. Let y be the reported violent crimes per 1000 residents. Six small cities in Arkansas (Blytheville, El Dorado, Hot Springs, Jonesboro, Rogers, and Russellville) reported the following information about x and y:

x 24.2 19.0 18.2 14.9 19.0 17.5 y 13.0 4.4 9.3 1.3 0.8 3.6 Complete parts

(a) through (e), given x 5 112.8, y 5 32.4, x2 5 2167.14, y2 5 290.14, xy 5 665.03, and r < 0.764.

(f) If the percentage of 16- to 19-year-olds not in school and not graduates reaches 24% in a similar city, what is the predicted rate of violent crimes per 1000 residents?
