Answer:
A. standard deviation = $500, expected return = $5,000
Step-by-step explanation:
For analysis which investment involved the least amount of risk we need to determine the coefficient of variation i.e. shown below:
As we know that
Coefficient of variance = standard deviation ÷ expected return
A = $500 ÷ $5,000 = 0.10
B = $700 ÷ $500 = 1.40
C = $900 ÷ $800 = 1.125
D = $400 ÷ 350 = 1.143
As it can be seen that investment A has the leas amount of risk hence, the same is to be considered
