Chebyshev’s theorem states that the proportion or percentage of any data set that lies within k standard deviation of the mean where k is any positive integer greater than 1 is at least 1 – 1/k^2. Below are four sample problems showing how to use Chebyshev's theorem to solve word problems.
Chebyshev's Theorem
mathcenter.oxford.emory.edu › site › math117This relationship is described by Chebyshev's Theorem: For every population of n values and real value k > 1, the proportion of values within k standard deviations of the mean is at least. 1 − 1 k 2. As an example, for any data set, at least 75% of the data will like in the interval ( x ¯ − 2 s, x ¯ + 2 s). To see why this is true, suppose a population of n values consists of n 1 values of x 1, n 2 values of x 2, etc. (i.e., n i values of each different x i in the population).

Trouble is, it’s not the interval we want: we’ve counted primes in (n;2n], whereas Chebyshev’s theorem counts primes in (0;n]. This problem is surmountable: Exercise 8.
