The article “Most Smokers Wish They Could Quit” (Gallup Poll Analyses, November 21, 2002) noted that smokers and nonsmokers perceive the risks of smoking differently. The accompanying relative frequency table summarizes responses regarding the perceived harm of smoking for each of three groups: a sample of 241 smokers, a sample of 261 former smokers, and a sample of 502 nonsmokers. Construct a comparative bar chart for these data. Do not forget to use relative frequencies in constructing the bar chart because the three sample sizes are different. Comment on how smokers, former smokers, and nonsmokers differ with respect to perceived risk of smoking.
