Consider the following data on two indexes of US and Japans equities: (Note: show work in full detail, include formulas and all)

	Mean Return	Standard Deviation
US	0.19	0.17
Japan	0.16	0.13

The correlation coefficient between returns on the US and Japan stocks is 0.6.

For the US and Japan:

1. Compute the weights for the minimum variance efficient (MVE) portfolio. You can use Solver to answer this question, but you need to explain in details, which problem your Solver actually solves. Alternatively, you can simply use calculus.
2. Write down your objective function with numbers plugged in.
3. What are you doing with this function?
4. What variable(s) can you choose?
5. Do you have any constraints? Write them down.

- What is the expected return and standard deviation of MVE portfolio? Show formulas you need to use to calculate both of them. Then show how you plug the data from this problem to obtain your numerical answers
