Use the data shown in the following table: K a. Compute the average return for each of the assets from 1929 to 1940 (the Great Depression). b. Compute the variance and standard deviation for each of the assets from 1929 to 1940. c. Which asset was the riskiest during the Great Depression? How does that fit with your intuition? Note: For all your answers type decimal equivalents.

Consider the following information: Rate of Return Probability of State State of if State Economy Recession of Economy .25 Occurs -.09 Normal .45 11 Вoom .30 .30 Calculate the expected return. (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) Expected return %

Calculate the expected value of the given random variable X. X is the number of tails that come up when a coin is tossed five times. E(X) =

3. * The force of interest (t) at time t (measured in years) is a + bt² where a and b are constants. An amount of £200 at time t = 0 accumulates to £210 at t = 5 and £230 at t = 10. 1 (a) Show that a = log (1.05) - 30 log(1.15) = 0.008352, and b = 250 log(1.15) - 125 log(1.05) = 0.0001687. (b) Compute A(0, 7) and hence compute the discounted value at t = 0 of a payment of £750 due at t = 7. (c) Compute A(6, 7). What is the equivalent constant annual interest rate for the year from t = 6 to t = 7? (d) Calculate the constant force of interest that would give rise to the same accumulation from t = 0 to t = 10.
