1. LSAT is an exam that university students
take if they are interested in applying to med school. A professor
said, "Because only a minority of university students take the
LSAT, the scores overestimate the ability of a typical university
student. The mean LSAT score is about 508, but I think that if all
the students took the test, the mean score would be no more than
450".
