Essay

A statistics professor asked her students whether or not they were registered to vote. In a sample of 50 of her students
(randomly sampled from her 700 students), 35 said they were registered to vote.
-According to a September 2004 Gallup poll, about 73% of 18- to 29-year-olds said that
they were registered to vote. Does the 73% figure from Gallup seem reasonable for the
professor's students? Explain.
