A state commission has been appointed to try to reduce crime. Commission analysts Philip Joseph and Rachel Maria have assembled data for 400 randomly selected cities. These data include whether police walk or do not walk a beat in the city, whether the city has fewer than the average number or more than the average number of streetlights for cities of the same size, and whether its crime rate is below the average or above the average for cities of the same size. Based on the accompanying data, what should Joseph and Maria recommend to the state commission in order to combat crime? Explain your answer.
