Net-Newsers In June of 2008, the Pew Research Foundation sampled 3615 U.S. adults and asked about their choice of news sources. They identified 13% as "Net-Newsers" who regularly get their news from online sources rather than TV or newspapers.
a) Pew reports a margin of error of ±2% for this result. Explain what the margin of error means.
b) Pew's survey included 2802 respondents contacted by landline and 813 contacted by cell phone. If the percentage of Net-Newsers is the same in both groups and Pew estimated those percentages separately, which group would have the larger margin of error? Explain.
c) Pew reports that 82% of the 470 Net-Newsers in their survey get news during the course of the day, far more than other respondents. Find a 95% confidence interval for this statistic.
d) How does the margin of error for your confidence interval compare with the values in parts a and b? Explain why.
