Last year, the typical college student graduated with $25,800 in debt (The Boston Globe, May 27, 2012). Let debt among recent college graduates be normally distributed with a standard deviation of $5,000. UseTable 1.

a.	What is the probability that the average debt of two recent college graduates is more than $28,000?(Round z value to 2 decimal places, and final answer to 4 decimal places.)
