You plan to invest $10,000 in a “complete” portfolio. The complete portfolio is comprised of a risky asset with an expected rate of return of 12% and a standard deviation of 15% and a treasury bill with a rate of return of 5%.
In order to have a “complete” portfolio with an expected rate of return of 9.0%, what is the Standard Deviation of your "complete" portfolio?
Enter as a number of percent without "%." Consider carrying calculations out to onehundredths of a percent. Thus 50.00% would be entered as "50" or as "50.00" but NOT as "50%" and not as "0.50"
