    4. The average speed of the train that leaves New York at 5 P. M. Is 60 miles per hour.

  5. A politician wrote the following: “I realize there are some short-comings to the questionnaire method. However, since I send a copy of the questionnaire to every home in the district, I believe the results are quite representative … I think the numbers received are so large that it is quite accurate even though the survey is not done scientifically.” The writer of the above statement makes which of the following assumptions:
