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?

Y = 247.5 +24X sb = 48 Sy/x = 35.0 r2 = .12
