Thanks!
14 0/2 points Consider the random variable X and its probabilty density function: X X₁ f(xi) x -4 0.2 Selected Answer - Incorrect X A second random variable is given by Y = 2X. Which of the following statements is true? (Multiple-Choice) -2 0.3 The variance of X is equal to 6.04 and the covariance between X and Y is 12.8. Selected Answer - Incorrect 0 0.1 X and Y are stochastically independent. 1 0.2 The conditional probabilities are fly3 | x4) = 0, f(y3 | x3) = 1 and it holds that E(y; | x₂) = -4. Selected Answer - Incorrect 3 0.2 It holds that E(x;|y2) = 0 and the expectation of Y is 1.2. ✓ The variance of Y is equal to 24.16 and the correlation coefficient between X and Y is 1.
