a.

To determine

Find the weighted average total return for the mutual funds using the number of funds as weights.

### Explanation of Solution

Calculation:

The total return and the number of funds for four categories of mutual funds are given.

The weighted mean of the data set can be obtained as follows:

The formula for the weighted mean is given below:

x¯=wixiwi

Here, xi indicate the observations and wi indicate the corresponding weights.

Substitute the values of xi and wi in the above formula.

x¯=9,191(4

b.

To determine

Check whether there is any difficulty associated with using the “number of funds” as the weights in computing the weighted average total return in part (a), and identify the requirements that might be used for weights.

c.

To determine

Find the expected return on the portfolio.
