Question: In 2012 Gallup published a report entitled Qatar s Rising Entrepreneurial

In 2012, Gallup published a report entitled “Qatar’s Rising Entrepreneurial Spirit” in which they concluded that the 33% of 1057 Qatari youth they surveyed who responded that they plan to start their own business was the highest in the region. They conducted a variety of face to face and phone interviews with Qatari youth during their survey. They noted that the margin of error was between 6.6 and 7.8 percentage points, and that “in addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.”
a) What kinds of bias might they be referring to?
b) Does their margin of error suggest that this was a simple random sample? Explain.
