Answer) Option D is the correct answer. A doubling of all x outcomes will not result in the doubling of variance. Because variance is based upon the degree of scatteredness along the mean value. If the mean doubles then the central tendency also changes. But the variation between the value remains constant.

Which of the following statements is necessarily false for some given (non-degenerate) risky prospect, X? An individual with convex utility of wealth will have a greater value of CE(X) than an individual with concave utility of wealth? When utility of wealth is linear, the numeric value (ignoring units) of CE(X) – EV(X) is equivalent to the numeric value of EU(X) – U(EV(X)). A doubling of all of X’s outcomes will result in a doubling of X’s expected value. A doubling...

An individual with convex utility of wealth will have a grealer value of CIİX individual with concave utility of wealth? when utility of wealth is linear, the numeric value (ignoring units) of CE(X)-EV(X) is equivalent to the numeric value of EUX) - U(EV(X). a. than an b, 1S c. A doubling of all of X's outcomes will result in a doubling of X's expected...
Pierce has a concave utility of wealth function, u(x). Pierce prefers prospect X to prospect Y. Which of the following statements is therefore necessarily true for Pierce? CE(X) > CE(Y). U(EV(X)) > U(EV(Y)) EU(X) < EU(Y) Y is a mean preserving spread of X.
Questions 1-4 rely on the following prompt Risky Prospect Y is defined as: Y = ($0, 0.25; $8, 0.50; $64, 0.25). Marco's utility of wealth function is given by u(x) = Vx (in case the font is too small, that says "fourth root of x”). 1. What is the value of EV(Y)? 2. What is the value of SD(Y) (the standard deviation of prospect Y (Round to the nearest hundredth). 3. What is the value of EU(Y) for Marco? 4....
Risky Prospect Y is defined as: Y (S0, 0.35; S16, 0.50: $81,0.15). Marco's utility of wealth function is given by u(x)-Vx (in case the font is too small, that says "fourth root of x"). 1. What is the value of EV(Y)? 2. What is the value of SD(Y (the standard deviation of prospect Y (Round to the nearest hundredth) 3. What is the value of EU(Y) for Marco? 4. What is Marco's certainty equivalent for Y (what is the value...
Questions 1 – 4 refer to prospects X and Y below, as well as the following information x = ($0,0.25;$50,0.50;$100,0.25) y = ($20,0.25;$50,0.50;$80,0.25) Mark has utility of wealth given by u(x)=x^0.4 1.) What is the expected value of prospect X (EV(X))? 2.) What is the standard deviation of prospect X (SD(X))? Round your answer to the nearest cent, and don’t worry, I’ll include a healthy margin of error so you won’t get this wrong due to rounding). 3.) What is...
Need help with stats true or false questions Decide (with short explanations) whether the following statements are true or false a) We consider the model y-Ao +A(z) +E. Let (-0.01, 1.5) be a 95% confidence interval for A In this case, a t-test with significance level 1% rejects the null hypothesis Ho : A-0 against a two sided alternative. b) Complicated models with a lot of parameters are better for prediction then simple models with just a few parameters c)...
