You may need to use the appropriate appendix table or technology to answer this question. In 2014, the Centers for Disease Control and Prevention (CDC) reported the percentage of people 18 years of age and older who smoke. Suppose that a study designed to collect new data on smokers and nonsmokers uses a preliminary estimate of the proportion who smoke of 0.30. (a) How large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of 0.02? Use 95% confidence. (Round your answer up to the nearest integer.) (b) Assume that the study uses your sample size recommendation in part (a) and finds 660 smokers. What is the point estimate of the proportion of smokers in the population? (Round your answer to four decimal places.) (c) What is the 95% confidence interval for the proportion of smokers in the population? (Round your answers to four decimal places.) to
