- Let (xn) be a
bounded sequence ((xn) is not necessarily convergent), and assume
that yn → 0. Show that lim n→∞ (xnyn) = 0.

All the
solution state that there exists M >0 and xn<=M . My question
is that why M always be bigger than 0 and Why it is bounded above ?
why it is not m<=xn bounded below????

Prove that if Xn is a sequence of random variables that converge to a limit X almost surely, then Xn converges to X in probability. Give an example to show that convergence in probability does not imply almost sure convergence. Suppose X bar is the mean of random sample of size 100 from a large population with mean 70 and standard deviation 20. Without use CLT , give the estimated probability P(65<x<75).
