12. A researcher investigates whether there is a relationship between the number of cigarettes a person smokes and whether the person wears a seat belt when driving. Their thinking is that people who smoke more are less concerned about their health and safety and therefore may be less inclined to wear seat belts. They collect the following data:

	Number of Cigarettes Smoked per Day
0	1-14 15-34	35 and over
Wear seat belts	175	20 42	6
Don't wear seat belts	149	17 41	9

a. At a 0.01 significance level, conduct a hypothesis test to test the claim that there is a relationship between the number of cigarettes a person smokes and whether the person wears a seat belt when driving. Show or explain your thinking.
