America's young people are heavy Internet users; 87% of Americans ages 12 to 17 are Internet users (The Cincinnati Enquirer, February 7, 2006). MySpace was voted the most popular Web site by 9% in a sample survey of Internet users in this age group. Suppose 1,650 youths participated in the survey. What is the margin of error (to 3 decimals), and what is the interval estimate (to 3 decimals) of the population proportion for which MySpace is the most popular Web site? Use a 95% confidence level.
