Data Analysis 4

• A Republican politician running for mayor wants
  to take a poll to determine if he is the favored
  candidate in the upcoming election. The mayoral
  candidate is scheduled to give a speech not at
  all related to the election at an upcoming town
  celebration. For convenience sake, his staff
  polls all of the people in attendance at the
  speech asking who they are planning to vote for
  in the upcoming mayoral election. The staff
  reports to the candidate that, based on the
  recent poll, he is favored by voters. Are the
  results of this poll most likely accurate or are
  they most likely misleading?
• A. The results of the survey are accurate as long
  as at least 100 people were polled
• B. The results of the poll are most likely
  misleading because the sample of people surveyed
  were voluntarily attending a speech given by the
  candidate and do not necessarily represent the
  population of the town.
• C. The results of the poll are most likely
  accurate because people are generally honest in
  declaring who they are going to vote for in
  elections.
• D. The results of the poll are misleading because
  recent advertisements are encouraging people to
  vote, creating a more opinionated population than
  usual.
