Unformatted text preview: seventy five percent will fall within two standard deviations. Third, at least 88.9 percent will fall within three standard deviations. Finally, at least 93.8 percent will fall within four standard deviations. These are the minimum percentages of data that must fall within within the specified number of standard deviations of the mean. However, if the distribution is mound-shaped, an even greater percentage of data will fall into the specified intervals, which involves the Empirical Rule. This theorem is good for almost everything, from butterflies to the orbits of the planets, because it can be applied to everything. As mentioned earlier, any set of data can be represented using Chebyshev’s theorem....
