The Pew Research Center for People and the Press interviewed 1,002 adult Americans and asked about the reason for a recent increase in sex scandals among elected officials. Fifty-seven percent of the respondents claimed that the increase is due to greater scrutiny by the media, while 19% felt that the increase is due to declining moral standards. The margin of error for the poll was 3 percentage points. Describe the population and the sample for this survey, and explain the meaning of the sample statistic of 57%. What can we conclude about the percentage of the population that believes the increase in political sex scandals is due to greater media scrutiny?
