garette smoking. In 2002, the prevalence of cigarette smoking among Americans was 21.1%. Data on evalent smoking in n=3,536 individuals who participated in a research study indicated that 482/3,536 = 13.6% of e respondents were currently smoking at the time of the study. Suppose we want to assess whether the revalence of smoking is lower among those in this study than in the rest of the country. Is there evidence of a tatistically lower prevalence of smoking in the research study as compared to the prevalence among all Americans? Explain your answer.
