Let et = -1, 0, 1, ... be a sequence of independent, identically distributed random variables with mean 1 and variance 4. Define a stochastic process by xt = (1/2)et - (1/4)et-1, t = 1, 2, ...i. Find E(xt)ii. Find V(xt)iii. Find Corr(xt, xt 1)iv. Find Corr(xt, xt 2)v. Is the series xt weakly dependent? Explain.

If X1, X2, X3, X4, X5 are independent and identically distributed exponential random variables with the parameter λ, compute (a) P{min(X1, …, X5) ≤a}; (b) P{max(X1, …, X5) ≤a}. | Numerade

Remember from the course Probability-the Science of Uncertainty and Data that i.i.d. stands for independent and identically distributed.A collection of random variables X1, …, Xn are i.i.d. if1. each Xi follows a distribution 𝐏i, all those distributions 𝐏i are the same, and2. Xi are (mutually) independentDecide which of the following collections are (approximately) i.i.d. (independent and identically distributed).(Choose all that apply.)People selected randomly (with replacement) by their addr
