Question

The average student loan debt for college graduates is $25,600. Suppose that that distribution is normal and that the standard deviation is $10,050. 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( , ) b Find the probability that the college graduate has between $7,050 and $20,300 in student loan debt. c. The middle 10% of college graduates' loan debt lies between what two numbers? Low: $ High: $
