I got this answer but i am unsure, please help me

A portfolio analyst invests in four different funds. She invests $600,000 in Fund A, which has a return of 6.5%; $500,000 in Fund B, which has a return of 4%; $450,000 in Fund C, which has a return of 5%, $100,000 in Fund D which has a return of 2%. Calculate the weighted mean percentage return. You may wish to use Excel. Round your answer to 2 decimal places, and do not enter the '%' symbol. For example, if you calculate that the weighted mean percentage return is 6.789%, enter 6.79. Hint: this looks very much like review question 2. 6.06
