Answer

Brief Explanations:

  1. Using a year - book to determine popular girl names in the US is likely to be a biased sample as year - books may not cover the entire population.
  2. Asking people exiting a vitamin store about exercise is biased since they are likely more health - conscious than the average American.
  3. Calling only Republican Party members to determine mayoral voter turnout is biased as it doesn't represent all voters.
  4. Sending a survey to every tenth employee of a company can be a systematic random sample and can fairly represent the company's employees' job satisfaction.
  5. Taking a poll in the main hallway between classes can be a convenient sample that may fairly represent students' interest in a school trip as it reaches a wide range of students during a common time.

Answer:

  • Sending a mandatory and confidential e - mail survey to every tenth employee of a company to determine overall job satisfaction.
  • Taking a poll in the main hallway between classes to determine the number of students who would be interested in a school trip to New York City.
