Problem 2.4. Suppose that X and Y are jointly continuous random variables and that Y = g(X) for some function g : ? ? ?. By explicitly calculating E[Y|X = x], show that E[Y|X] = Y.

Step 1
This is the expected value of Y given that X takes on the specific value x. Mathematically, it is defined as: E[Y|X = x] = ∫ y * f(y|x) dy where f(y|x) is the conditional probability density function of Y given X = x. Now, we are given that Y = g(X) for some Show more…

Let X be a continuous random variable with probability density function fX(x). Let g(X) be a continuous nonnegative function of X. If E{g(X)} exists, then for any positive constant a, prove that P{g(X) ≥ a} ≤ E{g(X)} / a.

(Independence) Suppose that X and Y are two continuous random variables with joint pdf f. Prove that X and Y are independent if and only if there exist functions g and h such that f(x,y) = g(x)h(y) for all x,y ∈ ℝ.
