Question
The average student loan debt for college graduates is $25,850. Suppose that that distribution is normal
and that the standard deviation is $10,900. Let X = the student loan debt of a randomly selected college
graduate. Round all probabilities to 4 decimal places and all dollar answers to the nearest dollar.
