Homework Help: Statistics

Posted by Sarah on Monday, April 30, 2012 at 1:38pm.

The author’s of the article “Perceived risks of Heart Disease and Cancer Among
Cigarette Smokers” expressed the concern that a majority of smokers do not view themselves as being at increased risk of heart disease or cancer. Because of this, the authors call for a public health campaign to educate smokers about the associated risks. In support of this recommendation, the authors offered the results of a study of 737 current smokers selected at random from the U.S. households with telephones. Of the 737 smokers surveyed, 295 indicated that they believe that they have a higher then average risk for cancer. Does this data suggest that the true proportion of smokers who view themselves as being at increased risk of cancer is, in fact, less than 0.05 as claimed by the authors of the paper?
