If you look up the word  empirical in a dictionary, you will find that it means “relying on experiment and observation rather than on theory.” Discuss the empirical rule in this context. The empirical rule certainly applies to the normal distribution, but does it also apply to a wide variety of other distributions that are not  exactly (theoretically) normal? Discuss the terms  mound-shaped and  symmetrical. Draw several sketches of distributions that are mound-shaped  and symmetrical. Draw sketches of distributions that are not mound-shaped or symmetrical.To which distributions will the empirical rule apply?
