$1.$ Ozarks Managed Care Inc. issued some callable bonds $19$ years ago with $30-$year life at their par value of $$1,000.$ These bonds pay $9\%$ coupon rate with annual payment. The firm just announced that these bonds are being called with $$100$ call premium. What is the yield$-$to$-$call of these bonds? Suppose the bond investors paid the par value at the time of issue. Please round your answer to $2$ decimal places and skip the $\%$ sign, e$.$g$.$ just put $1\mathrm{.}23$ instead of $1\mathrm{.}23\%.$
