    2) In 1999 the Center of Disease Control estimated that about 34.8% of high-school students smoked cigarettes. They established a national health goal of reducing that figure to 16% by the year 2010. To that end, they hoped to achieve a reduction to 30% by the end of 2001. Early in 2002 they released a research study in which only 28.5% of a random sample of 10,204 high-school student said they were current smokers. Is this evidence that progress toward the goal is on track?
