The College Boards, which are administered each year to many thousands of high school students, are scored so as to yield a mean of 500 and a standard deviation of 100. These scores are close to being normally distributed. A class of 16 students is from the reference population. What is the probability that the average SAT score of the class is between 450 and 600? Solution =500 =100 p(450.
