4.a. Draw the indifference curve in the expected return-standard deviation plane corresponding to a utility level of 0.05 for an investor with a risk aversion coefficient of 3. (Hint: use the following standard deviations: 0, 0.05, 0.1, 0.15,0.2, 0.25. For each one, find the expected rates of return providing a utility level of 0.05). b. Draw the indifference curve corresponding to a utility level of 0.05 for an investor with risk aversion coefficient A = 4. Comparing your answer to a, what do you conclude? c. Draw an indifference curve for a risk-neutral investor providing utility level 0.05. d. Draw the indifference curve for a utility level of 0.05 for a risk lover
