21. Cigarettes 2009 In 1999, the Centers for Disease Con- trol and Prevention 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 would be on track if they achieved a reduction to 17.7% by 2009. In 2009, they released a research study in which 19.5% of a random sample of 5080 high school students said they were current smokers. Is this evidence that progress toward the goal is off track? a) Write appropriate hypotheses. b) Verify that the appropriate assumptions are satisfied. c) Find the P-value of this test. d) Explain what the P-value means in this context. e) State an appropriate conclusion. f) Of course, your conclusion may be incorrect. If so, which kind of error did you commit?
