Question 10 1 pts Multiple questions require the following scenario. Bonds A and B are discount bonds with face value of $100. Assume yield to maturity on both bonds is 5%. Bond A has maturity of 10 years and bond B has maturity of 4 years. Suppose there is a 50% chance yields remain at 5%, a 25% chance yields rise to 6%, and a 25% chance that yields fall to 4%. Calculate the expected percent change in price of bond A Question 11 1 pts Question 11 1 pts Multiple questions require the following scenario. Bonds A and B are discount bonds with face value of $100. Assume yield to maturity on both bonds is 5%. Bond A has maturity of 10 years and bond B has maturity of 4 years. Suppose there is a 50% chance yields remain at 5%, a 25% chance yields rise to 6%, and a 25% chance that yields fall to 4%. Calculate the standard deviation of percent change in prices of bond B. Enter as a percent, round to two decimal places and do not enter a % sign D Question 12 1 pts Question 12 1 pts Multiple questions require the following scenario.

Bonds A and B are discount bonds with face value of $100. Assume yield to maturity on both bonds is 5%. Bond A has maturity of 10 years and bond B has maturity of 4 years. Suppose there is a 50% chance yields remain at 5%, a 25% chance yields rise to 6%, and a 25% chance that yields fall to 4%. Expected percent change in price for bond A is relative to bond B and bond A is than bond B. higher/less risky lower/less risky almost the same/less risky higher/risker Almost the same/risker Question 14 1 pts
