Data on 220 reported crimes is collected from district X in 2016. Suppose CS denotes the total cost to the state of offering crime protection services to this district (in
thousand dollars), LEOP denotes the number of law enforcement officers on patrol, DTP denotes the damage to public and private property (in thousand dollars), CCTV
denotes the number of CCTV cameras installed in the district, and Prison denotes the number of prison inmates The following table shows the results of a few
regressions of the total cost to the state.
