Question 7.5

5. On January 2, 2008, the American Idol website (www.americanidol.com) conducted an online poll that asked respondents which contestant they liked best among six former contestants. To become part of the sample, respondents simply clicked on a response. Of the 941,434 responses to this poll, 55% voted for Clay Aiken. We can conclude that

  1. most Americans preferred Clay Aiken out of those six contestants.
  2. the sample was too small a fraction of the millions of people who watched the TV show to draw any conclusion.
  3. the poll used voluntary response, so the results tell us little about the population of all adults.
