Transcribed Image Text:8. Newspapers lose their credibility when they are found to have published deceptive or misleading news stories. Researchers investigated whether certain national stereotypes occur more often in deceptive news stories than in authentic news stories. The researchers analyzed 174 news stories that were proven to be deceptive in nature and 138 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, and the accompanying printout gives a technology output for the data. Complete parts a through f below.
1 Click the icon to view the contingency table.
2 Click the icon to view the technology printout.
a. Find the sample proportion of negative tone news stories that are deceptive.
(Round to three decimal places as needed.)
b. Find the sample proportion of neutral news stories that are deceptive.
(Round to three decimal places as needed.)
c. Find the sample proportion of positive news stories that are deceptive.
(Round to three decimal places as needed.)
d. Compare the sample proportions, parts a-c. Does it appear that the proportion of news stories that are deceptive depends on story tone?
O A. Yes, because the proportions of deceptive stories do not vary by tone.
O B. No, because the proportions of deceptive stories do not vary by tone.
O C. No, because the proportions of deceptive stories vary by tone.
O D. Yes, because the proportions of deceptive stories vary by tone.
e. Give the null hypothesis for testing whether the authenticity of a news story depends on tone.
O A. Ho: The proportion of authentic negative stories is the same as the proportion of authentic positive stories.
O B. Ho: The proportion of authentic negative stories is not the same as the proportion of authentic positive stories.
OC. Ho: Authenticity and tone are independent.
O D. Ho: Authenticity and tone are dependent.
f. Use the accompanying technology printout to conduct the test, part e. Test at a = 0.05.
O A. Do not reject Ho. There is sufficient evidence that authenticity depends on tone.
OB. Reject Ho. There is not sufficient evidence that authenticity depends on tone.
OC. Do not reject Ho. There is not sufficient evidence that authenticity depends on tone.
O D. Reject Ho. There is sufficient evidence that authenticity depends on tone.
