1. You as a researcher are interested in studying domestic violence. To examine the problem, you select 50 domestic violence cases from Greene county and see whether there is a difference between who handles the case and whether an arrest is made of the suspect. You collect the following data.

	Arrest
	No	Yes	Total
Sheriff	2	5	7
Police Department	24	12	36
State Police	4	3	7
Total	30	20	50
