A group of 110 people, who lived at varying distances (in kilometers) from the 3 kilometer island nuclear power station, were asked if they thought a full evacuation of the area was required, when it went critical. The researches wanted to know if the opinion to evacuate or not depended on how far from the reactor people lived. The people were divided into 5 categories, based on the distance to the power station. Each person was given 3 choices: evacuation was needed, evacuation was not needed, they did not care about it. Evacuation needed x x x x -.. .-. --. Evacuation not needed X x x X X Do not care X x x X ... You are doing a Chi Square test for independence. Compute the degrees of freedom for this test.
