Roddy Richards invested​ $12014.88 in Wolverine Meat Distributors​ (W.M.D.) five years ago. The investment had yearly arithmetic returns of minus​9.7%, minus​8.1%, ​15%, 7.2%, and​ 15.4%. What is the arithmetic average return of Roddy​ Richard's investment?

Respuesta :

Answer:

The arithmetic average return would be 3.96%

Step-by-step explanation:

Given,

The returns in 5 years are,

-​9.7%, -​8.1%, ​15%, 7.2%, and​ 15.4%

We know that,

[tex]\text{Arithmetic average}=\frac{\text{Sum of all observations}}{\text{Number of observations}}[/tex]

Hence,

The arithmetic average return of the investment = [tex]\frac{-9.7-8.1+15+7.2+15.4}{5}[/tex]

[tex]=\frac{19.8}{5}[/tex]

= 3.96%
