Problem 2: In this problem, we let X1, X2, ..., Xn be iid Exp(1) random variables (i.e. exponential random variables with expectation equal to 1,
Problem 2: In this problem, we let X1, X2, ..., Xn be iid Exp(1) random variables (i.e. exponential random variables with expectation equal to 1, to simulate n of these, use rexp(n) ). a) Find the mean and variance of A = El, Xi. Find the mean and variance of B = 121, Xi. Which distribution does C = vn(B - 1) have when n is "large"
