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 statistical inference procedure should we use?
two‑sample t test
chi‑square test for two‑way table
chi‑square test for goodness of fit
matched pairs t test
