1. For the bond in question 5, find the convexity for a 50 bps change in yield-to-maturity (i= 0.5%).
2. For the bond in question, what is the percentage change in its price for a 0.5% increase in interest rate?
   1. What is the actual percentage change in price?
   2. What is the estimated percentage change in price using modified duration?
   3. What is the estimated percentage change in price using modified duration and convexity?
