In an effort to combat gun-related crimes, the city of Vancouver, Georgia, has initiated a guns-for-cash program in which citizens can turn in guns and receive cash in return (no questions asked). The city manager has collected data on the number of gun-related crimes per month (GCRIME) and the number of guns turned in per month (PGUN). Assist the manager by generating a regression equation with these data. What can you tell the manager about the effectiveness of the program?
