Since your RVs are independent, I'd take a look at Chernoff Bounds ( also )which are tighter. Note that the sum of independent Poisson RVs is also Poisson (in your case Poisson (30)), so it can be directly applied.

WebChebyshev inequality in statistics is used to add confidence intervals (95%) for the mean of a normal distribution. It was first articulated by Russian mathematician Pafnuty … WebJul 15, 2024 · Chebysev's inequality states a fact that is true for many probability distributions. For two standard deviations, it states that three-fourths of the data items will lie within two standard deviations from the mean. jeep crankshaftChebyshev's inequality states that at most approximately 11.11% of the distribution will lie at least three standard deviations away from the mean. Kabán's version of the inequality for a finite sample states that at most approximately 12.05% of the sample lies outside these limits. See more In probability theory, Chebyshev's inequality (also called the Bienaymé–Chebyshev inequality) guarantees that, for a wide class of probability distributions, no more than a certain fraction of … See more Chebyshev's inequality is usually stated for random variables, but can be generalized to a statement about measure spaces. Probabilistic statement Let X (integrable) be a random variable with finite non-zero See more Markov's inequality states that for any real-valued random variable Y and any positive number a, we have Pr( Y ≥a) ≤ E( Y )/a. One way to prove Chebyshev's inequality is to apply Markov's inequality to the random variable Y = (X − μ) with a = (kσ) : See more The theorem is named after Russian mathematician Pafnuty Chebyshev, although it was first formulated by his friend and colleague Irénée-Jules Bienaymé. … See more Suppose we randomly select a journal article from a source with an average of 1000 words per article, with a standard deviation of 200 words.
