What are the duration and modified duration of a seven-year, 3.5 percent coupon rate, annual coupon payment, $1000 par value government note priced today to yield 3 percent to maturity (use the text formulas or Excel's Duration and MDuration functions)?What is the convexity of this instrument?[Recall that Bonds and Bond Properties.xls illustrates these calculations.]Using one of the following approximation formulas with yield data in decimal form,

[if text formula]% Change in Price 100 (-1.0 Duration (YieldNew-YieldOld)/(1+YieldOld)),

[if Excel function]% Change in Price 100 (-1.0 MDuration (YieldNew-YieldOld)),

what is the approximate percentage change in this bond's price if yields on comparable securities rise to 4 percent?What is the actual percentage change in this bond's price if yields on comparable securities rise to 4percent (use a financial calculator or Excel's PV function)?
