Chebyshev's Inequality: Formula & Applications | CFA Level 1

SOLVED:Use Chebyshev's inequality to show that if X and Y are two arbitrary random variables satisfying E{(X-Y)^2}=0, then we have P(X=Y)=1, namely X and Y are almost surely identical. [Hint: P(|X-Y|>ϵ)=0 for any ϵ>0 .]

We saw that if we want to have a probability of at least 95% that the poll results are within 1 percentage point of the truth, Chebyshev's inequality recommends a sample size of n=50,000 . This is very large compared to what is done in practice. Newspaper polls use smaller sample sizes for various reasons. For each of the following, decide whether it is a valid reason. In the real world, a) the accuracy requirements are looser.b) the Chebyshev bound is too conservative. c) the people sampled are
