Answer:
The portfolio standard deviation is 14.82%
Explanation:
The portfolio standard deviation would be calculated by finding out the variance of the portfolio and taking the square root of it.
Variance of the portfolio = [(1 - .50)
x 0.25] + [0.50 x 0.16] + [2 x (1 - 0.50) x 0.50 x 0.25 x 0.16 x 0]
= [0.25 x 0.0625] + [0.25 x 0.0256] + [0]
= 0.015625 + 0.0064
VarPort = 0.022025
Std DevPort = √0.022025
Std DevPort = 0.1482 = 14.82 percent
The correct answer would be 81
Answer:
Income elasticity = 2
Normal good
Explanation:
Below is the given values:
Percentage decrease in consumers income = 10%
Percentage decrease in quantity demanded = 20%
Use the below formula to find the income elasticity:
Income elasticity = % change in quantity demanded / % in income
Income elasticity = -20/-10
Income elasticity = 2
Since the elasticity is 2 that means good is normal good.
