- If X is a continuous random variable with X ∼ Uniform([0, 2]), what is E[X^3]?Let X be a Poisson random variable with E(X) = 3. Find P(2 < x < 4).Suppose the random variable y is a function of several independent random variables, say x1,x2,...,xn. On first order approximation, which of the following is TRUE in general?
- Let x be a Poisson random variables. Find the probabilities for x using the Poisson Formula.Let X1 and X2 be independent random variables; X1 ∼ Poisson(2); X2 ∼ Poisson(3). Compute E(X1|X1 +X2 = 10).Let X1, X2, ... Xn random variables be independent random variables with a Poisson distribution whose parameters are l1, l2, ... ln, respectively. Which of the following is the moment generating function of the random variable Z defined as (the little image)?
- X1 and X2 are independent random variables such that Xi has PDF fXi(x)={λiexp(−λix) when x≥0, 0 otherwise}. What is P[X2<X1]?(b) Let Z be a discrete random variable with E(Z) = 0. Does it necessarily follow that E(Z³) = 0? If yes, give a proof; if no, give a counterexample.If X1 and X2 constitute a random sample of size n = 2from a Poisson population, show that the mean of thesample is a sufficient estimator of the parameter λ.
