A survey was carried out to find out if the occurrence of different kinds of natural disasters varies from on part of the town to the other. The town was divided into two as center town and town outskirts, and the natural disasters were divided into tornadoes, lighting, and fires.The survey showed these results:
Tornadoe Lightning Fires
Town Center 10 220 120
Town Outskirts 20 150 200
Do the above findings provide enough proof at 95 confidence level to indicate that the happening of natural disasters depends on the part of town?
I need some help as to how I would solve this question? so far, I thought I might need to set up a hypothesis and an alternative hypothesis, is that correct?
You can simply perform a chi-square test using a 2x3 contingency table. The result is a highly significant p value, confirming the hypothesis that differences exist between the two parts of the town.
