Chebyshev's theorem percentages
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… WebJan 20, 2024 · With the use of Chebyshev’s inequality, we know that at least 75% of the dogs that we sampled have weights that are two standard deviations from the mean. Two times the standard deviation gives us 2 x 3 = 6. Subtract and add this from the mean of 20. This tells us that 75% of the dogs have weight from 14 pounds to 26 pounds. Use of the …

Here we use Chebyshev’s inequality and work backward. We want 50% = 0.50 = 1/2 = 1 – 1/ K2. The goal is to use algebra to solve for K . We see that 1/2 = 1/ K2. Cross multiply and see that 2 = K2. We take the square root of both sides, and since K is a number of standard deviations, we ignore the negative solution to the equation.
WebSep 16, 2024 · Chebyshev's Theorem states that, for any distribution (normal or otherwise), the proportion of the data within k standard deviations of the mean is at least 1 - 1/k 2 So, in this case, we're given a mean of 1600 and standard deviation of 120. For part (a), the range defined is between 1240 and 1960. This is 360 data units below and above …
