A large randomized trial was conducted to assess the efficacy of Chantix for smoking cessation compared with bupropion (more commonly known as Wellbutrin or Zyban) and a placebo. Chantix is different from most other quit‑smoking products in that it targets nicotine receptors in the brain, attaches to them, and blocks nicotine from reaching them, while bupropion is an antidepressant often used to help people stop smoking. Generally healthy smokers who smoked at least 1010 cigarettes per day were assigned at random to take Chantix ( ?=352n=352 ), bupropion ( ?=329n=329 ), or a placebo ( ?=344n=344 ). The response measure is continuous cessation from smoking for Weeks 99 through 1212 of the study. A two‑way table of the results is given. Treatment Chantix Bupropion Placebo No smoke in weeks 9-12 155 97 61 Smokes in weeks 9-12 197 232 283 SOLVE: Calculate the percent of successes (no smoking in Weeks 99 – 1212 ) for each treatment.
