If an amount is zero, enter "0". 0 value(s) would be conSldered outlier(s). What does this suggest about the data? l Since there are outliers above the upper limit of the data, this is most likely why the mean is larger than the median. VI w " 0 Partially Correct Hint[s) Check My \"fork The following table shows the total return and the number of funds for four categories of mutual funds.

Using the number of funds as weights, compute the weighted average total return for these mutual funds (to 2 decimals] 30% b.15 there anyr difficulty associated with using the "number of fundsH as the weights in computing the weighted average total return in pait [a]? Discuss. What else might be used for weights? (i) Using r'number of funds" as weights will only be a good approXimation if the amount invested in various funds is approximatelyr equal. The amount invested in each fund could be used for weights. (ii) Using "number of funds" as weights results in a good approximation regardless of the amount invested in various funds. There is no need to use a different weight. (iii) Using "number of funds" as weights will only be a good apprommation if the amount invested in various funds is apprOXimately equal. There is no other option that could be used for weights. (iv) Using Hnumber of funds" as weights results in a good approximation regardless of the amount invested in various funds. The total amount invested in all funds could be used for weights. Choose the correct option. l Choice (i) v] \\'9 c.
