P8-10 Assessing return and risk Swift Manufacturing must choose between two asset purchases. The annual rate of return and the related probabilities given in the following table summarize the firm's analysis to this point.

For each project, compute: 1. The range of possible rates of return. 2. The average return. 3. The standard deviation of the returns. 4. The coefficient of variation of the returns. b. Construct a bar chart of each distribution of rates of return. c. Which project would you consider less risky? Why?
