The average student loan debt for college graduates is $25,250. Suppose that that distribution is normal and that the standard deviation is $12,450. 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.
a. What is the distribution of X? X ~ N(
25,250
