Question: Consider the following city populations and numbers of homicides, determine which city has the most serious homicide problem. You have to transform these numbers into something that you can compare.

Washington, D.C. pop. 4,212,789 homicides = 895

Louisville, KY pop. 1,001,001 homicides = 45

Podunk, AR pop. 12,421 homicides = 10

At first glance, which city looks to have the most serious problem? Which one actually does? How do you make these figure comparable (what do you have to do?) and why is this process useful when you are trying to make comparisons like this?
