Exercise 3:
Suppose that an electrical engineering firm in Ottawa opens seventy new posi-
tions. One thousand undergraduate students accross Canada show up for these
positions. To select the best 70 from among the applicants, the firm gives a test
that covers electrical skill, manual dexterity, and mathematical ability. The
mean grade on this test turns out to be 60, and the scores have a standard
deviation of 6. Can an undergraduate who scores 84 count on getting one of the
jobs? Assume that the grade distribution is symmetric about the mean.
