Answer:
6.35%
Explanation:
you can use the yield to maturity formula to determine the coupon:
YTM = {coupon + [(face value - market value) / n]} / [(face value + market value) / 2]
0.065 = {coupon + [(1,000 - 984.56) / 15]} / [(1,000 + 984.56) / 2]
0.065 = {coupon + 1.029} / 992.28
64.4982 = coupon + 1.029
coupon = 63.47
coupon rate = 63.47 / 1,000 = 0.06347 = 6.35%
