- Let the random variable X be defined on the support set (1,2) with pdf fX(x) = (4/15)x3, Find the variance of X.arrow_forwardLet X∼Uniform(0,1) distribution. Find the PDF of Y= 3√X and derive the expected value and the variance of Y.arrow_forwardLet f(x, y) = x + y for 0 < x < 1 and 0 < y < 1 The Conditional Variance of Y when X = ; isarrow_forward
- Let X be a random variable and Y = aX + b with a ̸= 0. Show that the correlation between X and Y is either +1 or −1. State the conditions which make the correlation equal to +1.arrow_forwardLet X be a random variable distributed as a Normal with mean 0 and variance 2 (i.e., X ~ N(0, 2)). Let Y be a random variable distributed as a Normal with mean 2 and variance 3 (i.e.., Y ~ N(2, 3)). X and Y are independent. What is the distribution of 2X – 5Y ?arrow_forwardLet Y1, . . . , YN be a random sample from the Normal distribution Yi ∼ N(ln β, s2) where s2 is known. Find the Score function, the estimating equation and the information matrix.arrow_forward
