Suppose a school district decides to randomly test high school students for attention deficit disorder (ADD). There are three high schools in the district, each with grades 9-12.
 
  The school board pools all of the students together and randomly samples 250 students. Is this a simple random sample?
  A) Yes, because each student is equally likely to be chosen.
  B) Yes, because they could have chosen any 250 students from the district.
  C) Yes, because the students were chosen at random.
  D) No, because we can't guarantee that students from each school in the sample.
  E) No, because we can't guarantee that students from each grade in the sample.

Question 2

The January 2005 Gallup Youth Survey telephoned a random sample of 1,028 U.S. teens and asked these teens to name their favorite movie from 2004. Napoleon Dynamite had the highest percentage with 8 of teens ranking it as their favorite movie.
 
  Which is true?
  I. The population of interest is all U.S. teens.
  II. 8 is a statistic and not the actual percentage of all U.S. teens who would rank this movie as their favorite.
  III. This sampling design should provide a reasonably accurate estimate of the actual percentage of all U.S. teens who would rank this movie as their favorite.
  A) II only B) I only C) III only D) I, II, and III E) I and II
