Answer:
0.2
Explanation:
Data provided as per the given question
Mean = 15%
Variance = 9%
Standard deviation = 3%
The computation of return on equity is shown below:-
Coefficient variance = (Standard deviation ÷ Mean)
= 0.03 ÷ 0.15
= 0.2
Therefore for computing the coefficient variance we simply divide standard deviation from the mean.
