A research article described a simple random sample of 584 smokers who tried to quit smoking by using either a nicotine patch or e-cigarettes (fake cigarettes producing nicotine in water vapor form). After six months, 7.3% of those using e-cigarettes had stopped smoking, compared with 5.8% of those wearing the patch. To see if quitting result is significantly associated with the method used, which of the following statistical inference procedure should we use?

Question

We are comparing the quitting rates between two groups, those using e-cigarettes and those using nicotine patches. Since we are comparing two categorical variables (method used and quitting status) in a 2x2 table, the best choice is the chi-square test for two-way table. This test can help us determine whether there is a significant association between the method used and quitting result.
