13. Variance and Standard Deviation (expected). Using the data from problem 13‚ calculate the variance and standard deviation of the three investments‚ stock‚ corporate bond‚ and government bond. If the estimates for both the probabilities of the economy and the returns in each state of the economy are correct‚ which investment would you choose considering both risk and return? Why? ANSWER Variance of Stock = 0.10 x (0.25 – 0.033)2 + 0.15 x (0.12 – 0.033)2 + 0.50 x (0.04 – 0.033)2 + 0

Analysis of Variance Lecture 11 April 26th‚ 2011 A. Introduction When you have more than two groups‚ a t-test (or the nonparametric equivalent) is no longer applicable. Instead‚ we use a technique called analysis of variance. This chapter covers analysis of variance designs with one or more independent variables‚ as well as more advanced topics such as interpreting significant interactions‚ and unbalanced designs. B. One-Way Analysis of Variance The method used today for comparisons of

Assignment 7: Mean-Variance Portfolio Theory ------------------------------------------------- Top of Form 1 . Consider‚ as in Lecture 7.1‚ a portfolio of two risky assets‚ with expected returns rˉ1‚rˉ2‚ variances σ21‚σ22 and covariance σ1‚2. No other assets are available. You have to allocate $1 mln of investment in the portfolio of the two assets in order to minimize total portfolio variance. What is the optimal amount of investment in asset 1 (in mln dollars)?
