Chebyshev's Inequality: given probability, find $k$
math.stackexchange.com › questions › 2053480
the formula to this theorem looks like this: P ( μ − k σ < x < k σ + μ) ≥ 1 − 1 k 2. where k is the number of deviations, so since above I noted that the values between 110 and 138 are 2 deviations away then we will use k = 2. We can plug in the values we have above: P ( 124 − 2 σ < x < 2 σ + 124) ≥ 1 − 1 2 2. =.

19.04.2021 · Consequently, Chebyshev’s Theorem tells you that at least 75% of the values fall between 100 ± 20, equating to a range of 80 – 120. Conversely, no more than 25% fall outside that range. An interesting range is ± 1.41 standard deviations. With that range, you know that at least half the observations fall within it, and no more than half ...
