Answer:
Variance = 0.02141851
Explanation:
We first calculate the mean for the stocks
Mean = (0.1858 - 0.0558 + 0.2081) / 3
Mean = 0.3381 / 3
Mean = 0.1127
Variance = [(0.1858 - 0.1127)^2 + (- 0.0558 - 0.1127)^2 + (0.2081 - 0.1127)^2] / 3 -1
Variance = [0.0731^2 + (-0.1685^2) + 0.0954^2] / 2
Variance = 0.00534361 + 0.02839225 + 0.00910116 / 2
Variance = 0.04283702 / 2
Variance = 0.02141851
The variance of returns is 0.02141851

Answer:
6.34
%
Explanation:
For computing the coupon rate, first we have to determine the PMT by using the PMT formula that is shown on the attachment
Given that,  
Present value = $939.02
Future value = $1,000
Rate of interest = 7.15% ÷ 2 = 3.58%
NPER = 11 years × 2 = 22 years
The formula is shown below:
= PMT(Rate;NPER;-PV;FV;type)
The present value come in negative
So, after solving this, the PMT is $31.70
It is semi annually
Now the annual PMT is 
= $31.70 × 2
= $63.40
So, the coupon rate equals to
= $63.40 ÷ $1,000
= 6.34
