The June 2003 report on Views of a Changing World , conducted by the Pew Global Attitudes Project ( www.people-press.org ), discussed changes in views of the United States by other countries. In the largest Muslim nation, Indonesia, a poll conducted in May 2003 after the Iraq war began reported that 83% had an unfavorable view of America, compared to 36% a year earlier. The 2003 result was claimed to have a margin of error of 3 percentage points. How can you approximate the sample size the study was based on?
