2.  Guns and Murder Rate Using data collected from the FBI and the Bureau of Alcohol, Tobacco, and Firearms, the number of registered automatic weapons and the murder rate (in murders per 100,000 people) was obtained for each of eight randomly se- lected states. STATDISK was used to find that the value of the linear correlation coef- ficient is r 5 0.885.
