Indiana University posts the grade distributions for its courses online."' In one spring semester, students in Math 118 received 16.1% As, 34.3% B's, 29.2% Cs, 9.6% D's, and 9.8% F's. Math 118 is a large enough course that we can take the grades of an SRS of 25 students and not worry about the finite population correction factor. If x is the average of these 25 grades, what are the mean and standard deviation of x?
