Chebyshev's theorem states that for any set of numbers, the fraction that will lie within K standard deviations of the mean is at least 1-1/k^2. Use this theorem to find the fraction of all the numbers of a data set that must lie within 3 standard deviations from the mean. At least____of all numbers must lie within 3 standard deviations from the mean. ( Type an integer or a fraction)
