WebAnswer: 55.56%. For any shaped distribution, at least 55.56% of the data values will lie within 1.5 standard deviation(s) from the mean. That is, from 1.5 standard deviations below the mean to 1.5 standard deviations above the mean. WebSep 12, 2015 · Cheb.Ineq: P ( X − μ ≥ a) ≤ V a r ( X) a So I'm starting with Markov's Inequality: P ( X − μ ≥ a) ≤ E ( X − μ ) a I replace X − μ by ( X − μ), and square both sides, which leads to: P ( ( X − μ) 2 ≥ a 2) ≤ E ( ( X − μ) 2) a 2 The numerator of the right hand side is the variance of X. So we get: P ( ( X − μ) 2 ≥ a 2) ≤ V a r ( X) a 2 attorney in louisville kentucky

WebChebyshev's inequality has many applications, but the most important one is probably the proof of a fundamental result in statistics, the so-called Chebyshev's Weak Law of Large … Chebyshev'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 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. We can then infer that the probability … 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 See more Chebyshev's inequality is usually stated for random variables, but can be generalized to a statement about measure spaces. Probabilistic statement See more As shown in the example above, the theorem typically provides rather loose bounds. However, these bounds cannot in general (remaining true for arbitrary distributions) be improved upon. The bounds are sharp for the following example: for any k … See more Several extensions of Chebyshev's inequality have been developed.
