Answer:
The correct answer is C. 7.22 percent
Explanation:
To find the arithmetic risk premium for the 5 year period, the formula is
Average risk premium for the period = Sum of risk premium for each year / number of years = ∑ra(i) - rf(i) / n
ra = asset or investment return / 100
rf = risk free return / 100
Where i represents each year.
Sum of risk premium for each year = (0.187 - 0.052) + (0.058 - 0.034) + (0.079 - 0.028) + (0.108 - 0.034) + (0.116 - 0.039) = 0.361
Average risk premium = 0.361 / 5 = 0.0722 = 7.22 / 100 = 7.22 percent
