The Normal police chief wants to know whether police car cruising has any impact on crime rates.
Question:
The Normal police chief wants to know whether police car cruising has any impact on crime rates. Of the city’s 10 precincts, 5 are cruised regularly, and the other 5 are never cruised (police do respond to calls in these precincts). At the end of a test period, the police chief takes the crime rate (Y) in each precinct and regresses it on a dummy variable coded 1 for cruising and coded 0 for no cruising (X). From the following regression equation, what can you say about police cruising and crime rates in Normal?
