Step 1: Introduction:

Empirical rule states that:

About 68% of observations lie within one standard deviation of the mean. That is, in the interval $open parentheses mu minus sigma comma space mu plus sigma close parentheses$ .
About 95% of observations lie within two standard deviations of the mean. That is, in the interval $open parentheses mu minus 2 sigma comma space mu plus 2 sigma close parentheses$ .
About 99.7% of observations lie within three standard deviations of the mean. That is, in the interval $open parentheses mu minus 3 sigma comma space mu plus 3 sigma close parentheses$ .
