Suppose 150 people take a quiz, and say the mean score was a 100 out of 200 points, with a standard deviation of 40. Suppose the scores are distributed in a normal probability distribution. Approximately how many people got above a 180? What is the probability that someone got between a 91 and 157 on the quiz? (round your answer to three digits after the decimal).
