B3 (10 marks). Agatha values an uncertain income y, according to the expected utility index EU-y-rVar() where y is the mean income, Var(y) is the variance and r measures Agatha's degree of risk aversion. Agatha rents a plot of land runs and, in return for a fixed rent F which she pays to a landlord, she gets to keep a share B of the output z. It follows that her income is given by Suppose, for simplicity, the output is...

2. A financial analyst measures the monthly returns of two stocks (A and B) over a twenty year period. Over that time period, stock A had an average return of 11% (per year) with a standard deviation of 20%. Over that same period, stock B had an average return of 13% with a standard deviation of 17%. The analyst estimates the CAPM for both stocks. The results are below: Stock A: SUMMARY OUTPUT Regression Statistics Multiple R 0.734020234 R Square...
Question 1 (20 points: Events, counting, and properties f probabniny Consider the network shown below. There are two kinds of links in the network. Each link of kind o-p +0 fails with probability p and that of kind O 4+0 fails with probability q. Each link is assumed to fail independently of the other. We say that a path is successful if no link in the path fails. For example, the path S-B-T succeeds if none of the links S...
For each of the following statements, identify whether the statement is true or false, and explain why. Please limit each response to no more than 2 sentences. a) The probability that a continuous random variable takes a specific value is 0. b) Statistical inference is the process of drawing conclusions about unknown statistics by using known parameters. c) The terms “histogram” and “bar graph” are synonyms. d) If two events A and B are independent, then there is no overlap...
