Notice that the inequality below states that you can upper bound the two-sided tail probability that the sample mean Y ¯ deviates from the theoretical mean μ by more than ϵ in terms of some exponential function. P ( Y n ¯ − μ ≥ ϵ) ≤ 2 e − 2 n ϵ 2 / ( b − a) 2. Via complementary events, that this ...

In probability theory, Hoeffding's inequality provides an upper bound on the probability that the sum of bounded independent random variables deviates from its expected value by more than a certain amount. Hoeffding's inequality was proven by Wassily Hoeffding in 1963.
