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

The emphasis in applied linguistics is on language users and the ways in which they use languages‚ contrary to theoretical linguistics which studies the language in the abstract not referring it to any particular context‚ or language‚ like Chomskyan generative grammar for example. Interestingly even among applied linguists there is a difference 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)? Assume expected returns are

One-way Analysis of Variance (Abbreviated one-way ANOVA) is a technique used to compare means of two or more samples (using the F distribution). This technique can be used only for numerical data. It consists of a single factor with several levels and multiple observations at each level. With this kind of layout we can calculate the mean of the observations within each level of our factor. The residuals will tell about the variation within each level. It can also average the means of each level
