Chapter 7, Problem 1LCWP

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 symmetric. Draw several sketches of distributions that are mound-shaped and symmetric. Draw sketches of distributions that are not mound-shaped or symmetric. To which distributions will the empirical rule apply ?
