Question:

A column by New York Times columnist Nicholas Kristof (August 15, 2003) discussed results of polls indicating that religious beliefs in the United States tend to be quite different from those in other Western nations. He quoted recent Gallup and Harris polls of random samples of about 1000 Americans estimating that 83% believe using the Virgin Birth of Jesus but only 28% believe in evolution. A friend of yours is skeptical, claiming that it’s impossible to predict beliefs of over 200 million adult Americans by interviewing only 1000 of them. Write a one-page report using this context to show how you could explain about random sampling, the margin of error, and how a margin of error depends on the sample size.
