Scores on the LSAT are approximately normally distributed. In fact, published reports indicate that approximately 40 percent of all test takers score at or between 145 and 155, and about 70 percent score at or between 140 and 160. The full range of scores is 60 pts (120–180). Using your knowledge of normal distributions, estimate the mean, median, and the standard deviation of the LSAT.
