From the details that are contained in the question, the portfolio standard deviation is 0.0544 or 5.44%
<h3>How to solve for the portfolio standard deviation</h3>
w1 = weight of euros 1 = 500000/800000
w2 = weight of canadian dollars = 300000/800000
Standard deviation 1 = 8%
Standard deviation 2 = 3%
Correlation coefficient = 0.30
(w1*σ1)² + (w2*σ2)² + (2* w1*σ1* w2*σ2 * 0.30)^0.5

Therefore the portfolio standard deviation is given as 0.0544 or 5.44%

Answer:
$2 billion
Explanation:
Foreigners spend $7 billion on U.S net exports
Americans spend $5 billion on imports
Therefore the value of U.S net exports can be calculated as follows
