Kohls Corp.$\text{'}$s $7\mathrm{.}5\%$ coupon bonds maturing in $15$ years traded yesterday at $956\mathrm{.}77.$ Assume semi$-$annual compounding.

What was the bond's yield to maturity?

Always carry at least four decimal places throughout your analysis.

Response should include $4$ decimal places. Do not include percentage sign $($for example, $12\%$ would be entered as $0\mathrm{.}1200).$ Do not include a dollar sign. Do not include comma $($for example, $15,000$ would be entered as $15000).($Trailing zeroes may disappear$--$do not worry about that$)$
