A local researcher is interested in if there was any relation between Cannabis use and traffic accident. She collected responses for Cannabis use (Yes or No on regular basis) and whether they have had any traffic accident (Yes or No) in the past one year among a random sample of 40 people. The table below summarizes the data (table entries represent raw frequencies of people falling in those categories). Using alpha =.01, use the appropriate statistic to help Dr. Stork check out her hunch.

		Cannabis
		No	Yes
Accident	No	14	9
Yes	8	9
