Average return b-1. Variance b-2. Standard deviation

Explanation / Answer

The correct answer is :

a.

Mean = ( 12%- 12% +19%+24%+10%) /5

= 10.6%

Hence the correct answer is 10.6%

b. Variance = Standard Deviation ^ 2

= 13.81303732 % ^ 2

= 190.80

= 0.19080

Hence the correct answer is 0.19080

b-2. Standard Deviation = [ Sum of Deviation Squared / (Time -1) ] ^ ( 1/2)

= [ 763.20 / ( 5-1) ] ^ ( 1/2)

= 13.81303732%

= 13.81%

Hence the correct answer is 13.81%

a. Average Return 10.6% b-1. Variance 0.19080 b-2. Standard Deviation 13.81%
