I’m working on a Mathematics exercise and need support.

You have been given the following return data(excel attached), on 3 assets-A,B and C – over the period 2021-2024. Using these assets, you have isolated three investments alternatives(excel attached). (Round to two decimal places.)

a. Calculate the average portfolio return for each of the three alternatives.

b. Calculate the standard deviation of returns for each of the three alternatives.

c. On the basis of your findings in parts a and b, which of the three investment alternatives would you recommend? Why?
