Chapter 8, Problem 51SE
Russia has recently started a push for stronger smoking regulations much like those in Western countries concerning cigarette advertising, smoking in public places, and so on. The DATAfile named Russia contains sample data on smoking habits of Russians that are consistent with those reported by The Wall Street Journal (The Wall Street Journal, October 16, 2012). Analyze the data using Excel and answer the following questions.
- a. Develop a point estimate and a 95% confidence interval for the proportion of Russians who smoke.
- b. Develop a point estimate and a 95% confidence interval for the
mean annual per capita consumption (number of cigarettes) of a Russian. - c. For those Russians who do smoke, estimate the number of cigarettes smoked per day.
