Cigarette taxes New York public health officials report that currently 22% of adults smoke (Ithaca Journal, 1/12/04). They hope that newly increased state cigarette taxes will reduce this rate. They plan to check in December by selecting a random sample of 1200 New Yorkers to estimate again the percentage of adults who smoke.
