Below are four sample problems showing how to use Chebyshev's theorem to solve word problems. Saw et al extended Chebyshev's inequality to cases where the population mean and variance are not known and may not exist, but the sample mean and sample standard deviation from N samples are to be employed to bound the expected value of a new drawing from the same distribution. The following simpler version of this inequality is given by Kabán. where X is a random variable which we have sampled N times, m is the sample mean, k is a co…
