"Misperceptions, the Media and the Iraq War," published by the Program on International Policy Attitudes in October 2003, explored the relationship between Americans' primary news source and their susceptibility to misperceptions about the war in Iraq.37 Specifically, besides reporting their primary source of news, a representative sample was asked if Iraq-al Qaeda links had been found, if weapons of mass destruction had been found, and if world public opinion favored the war. This table shows counts consistent with the reported frequency of each of the primary news sources, and how many of those respondents harbored at least one major misperception about the war.
a. How many degrees of freedom apply?
b. Use software to carry out a chi-square test; report the chi-square statistic.
c. Report the P-value to confirm that having misperceptions was related to where respondents obtained their news.
d. Which two sources corresponded to the highest percentages of people with misperceptions?
e. Which two sources corresponded to the lowest percentages?
f. Which four sources corresponded to the largest terms in the calculated chi-square statistic?
