A BBB-rated corporate bond has a yield to maturity of 9.5 %. A U.S. treasury security has a yield to maturity of 7.8 %. These yields are quoted as APRs with semiannual compounding. Both bonds pay semi-annual coupons at a rate of 8.8 % and have five years to maturity. a. What is the price (expressed as a percentage of the face value) of the treasury bond? b. What is the price (expressed as a percentage of the face value) of the BBB-rated corporate bond? c. What is the credit spread on the BBB bonds?

Assume that the time needed to complete a midterm exam for a particular course is normally distributed with a mean of 90 minutes and a standard deviation of 15 minutes.
5- What percentage of the class is expected to complete the exam within 60 minutes?
6- What percentage of the class is predicted to NOT complete the exam within 115 minutes?
7- If the time limit is 100 minutes and there are 200 students in the class, how many of them do you predict to not complete the exam within the allocated time?
