Answer: The standard deviation of the stock is 3.23 percentage
Explanation:
First we shall calculate the epected weighted average return of the stock.
We shall multiply the probability of the scenario with its expected return and then take the sum of the expected returns of different scenarios,
E(x) = (0.2 x 14%) + (0.7 x 8%) + (0.1 x 2%)
E(x) = 8.6%
We shall use the follwing formula to calculate the Variance of the stock,
σ²(x) = ∑ P() × [
- E(r)]²
σ²(x) = (0.2) (0.14 - 0.086)² + (0.7) (0.08 - 0.086)² + (0.1) (0.02 - 0.086)²
σ²(x) = 0.001044
To find the standar deviation,
σ(x) =
σ(x) = 0.0323109
in percentage it would be 3.23%
Answer:
The growth rate of the U.S economy in 2011 was 5.65%
Explanation:
This is a simple calculation
We use this formula to calculate percent changes from one period to another:
% change =
We have that the GDP for 2010 was $11,150 billion and the GDP in 2011 was $11,780 billions we then apply the formula:
% change =
% change =
This means that the growth rate of the U.S economy in 2011 was 5.65%
