Consider the following probability distribution of returns estimated for a proposed project that involves a new ultrasound machine: Rate of Return State of the Economy Probability of Occurrence Very poor Poor Average Good Very good 0.10 0.20 0.40 0.20 0.10 10.0% 2.0% 14.0% 22.0% 34.0% a. What is the expected rate of return on the project? .10x (-10%) + .20 x (096) + .40 x (10%) + .20 x (20%) + .10 x (30%) b. What is the project's standard deviation of returns? 2.80% c. What is the project's coefficient of variation (CV) of returns? 10% d. What type of risk do the standard deviation and CV measure? e. In what situation is this risk relevant
