Answer:
8.96%(9.0% rounded to 1 decimal place since YTM of 9.7% was also to 1 decimal place)
Step-by-step explanation:
In ascertaining the coupon rate, we need to, first of all, determine the semiannual coupon payment(since the bond pays coupons on a semiannual basis) of the bond using a financial calculator bearing in mind that the calculator would be set to its default end mode before making the following inputs:
N=24(number of semiannual coupons in 12 years left to maturity=12*2=24)
I/Y=4.85(semiannual yield to maturity without the "%" sign=9.7%/2=4.85%)
PV=-948( the current bond price of $948 shown as a negative since it is an outflow of cash for the bond investor)
FV=1000(the bond face value of $1000)
CPT
PMT=$44.79
semiannual coupon=face value*coupon rate/2
$44.79=$1000*coupon rate/2
$44.79*2==$1000*coupon rate
$89.58=$1000*coupon rate
coupon rate=$89.58/$1000
coupon rate=8.96%
