Textbook Question

Chapter 10, Problem 10.45ACB

Stereotyping in deceptive and authentic news stories. Major newspapers lose their credibility (and subscribers) when they are found to have published deceptive or misleading news stories. In Journalism and Mass Communication Quarterly(Summer 2007), University of Texas researchers investigated whether certain stereotypes (e.g., negative references to certain nationalities) occur more often in deceptive news stories than in authentic news stories. The researchers analyzed 183 news stories that were proven to be deceptive in nature and 128 news stories that were considered authentic. Specifically, the researchers determined whether each story was negative, neutral, or positive in tone. The accompanying table gives the number of news stories found in each tone category.

	Authentic News Stories	Deceptive News Stories
Negative tone	59	111
Neutral tone	49	61
Positive tone	20	11
Totals	128	183

Based on a survey of 12,344 U.S. college students and 6,729 Canadian college students, Kuo, Adlaf, Lee, Gliksman, Demers, and Wechsler (2002) report that alcohol use is more common among Canadian than U.S. students, but heavy drinking (five or more drinks in a row for males, four or more for females) is significantly higher among U.S. students than Canadian students. Is this an example of a survey research design?

Teen smoking, part I A Vermont study published by the American Academy of Pediatrics examined parental in-fluence on teenagers’ decisions to smoke. A group of stu-dents who had never smoked were questioned about their parents’ attitudes toward smoking. These students werequestioned again two years later to see if they had started smoking. The researchers found that, among the 284 stu-dents who indicated that their parents disapproved of kids smoking, 54 had become established smokers. Among the 41 students who initially said their parents were le-nient about smoking, 11 became smokers. Do these data provide strong evidence that parental attitude influencesteenagers’ decisions about smoking?a) What kind of design did the researchers use?b) Write appropriate hypotheses.c) Are the assumptions and conditions necessary forinference satisfied?d) Test the hypothesis and state your conclusion.e) Explain in this context what your P-value means.f) If that conclusion is actually wrong, which type…
