I was hoping that someone could help me determine the two questions marks (?). that is the missing expected return value and the standard deviation value.
Second...these correlation matrixs keep appearing in my questions but so far i have never had to use them. What are they they for...what do they tell us?
If anyone can help with this i would be extremely greatly. Thank you!http://img692.imageshack.us/img692/3771/matrixn.jpg
