Suppose you know a dataset has a mean of 100 and a standard deviation of 10, and you’re interested in a range of ± 2 standard deviations. Two standard deviations equal 2 X 10 = 20. Consequently, Chebyshev’s Theorem tells you that at least 75% of the values fall between 100 ± 20, equating to a range of 80 … See more Chebyshev’s Theorem helps you determine where most of your data fall within a distribution of values. This theorem provides … See more The Empirical Rule also describes the proportion of data that fall within a specified number of standard deviations from the mean.

WebOct 1, 2024 · Solution: The interval (22, 34) is the one that is formed by adding and subtracting two standard deviations from the mean. By Chebyshev’s Theorem, at least 3 / 4 of the data are within this interval. Since 3 / 4 of 50 is 37.5, this means that at least 37.5 observations are in the interval.
