The portfolio manager at MFM Manufacturers has to choose between the execution of two competing projects, namely,
project A and project B. The mean-variance rule can be used to choose between these projects. The mean-variance rule
states that an investment in project A will be preferred to an investment in project B, provided that (i) ______ or (ii) ______.
a.
(i) either the mean expected return on project A exceeds that of project B and the variance of project A is equal to or
less than that of project B; (ii) the mean expected return on project A exceeds or is equal to the expected return on
project B and the variance of project B is greater than that of project A
b. (i) either the mean expected return on project A exceeds that of project B and the variance of project A is equal to or
more than that of project B; (ii) the mean expected return on project A exceeds or is equal to the expected return on
project B and the variance of project B is greater than that of project A
c. (i) either the mean expected return on project A exceeds that of project B and the variance of project A is equal to or
more than that of project B; (ii) the mean expected return on project B exceeds the expected return on project A
d. (i) either the mean expected return on project B exceeds that of project A and the variance of project B is equal to or
more than that of project A; (ii) the mean expected return on project B exceeds or is equal to the expected return on
project A and the variance of project A is greater than that of project B
