Four years ago, Dorothy Stills bought six-year, 5.3 percent coupon bonds issued by the Sandhill Corp. for $945.48. If she sells these bonds at the current price of $891.86, what will be her realized yield on the bonds? Assume similar coupon-paying bonds make annual coupon payments. Assume face value is $1,000. (Round intermediate calculations to 5 decimal places, e.g. 1.25145 and final answer to 2 decimal places, e.g. 15.25%.)
