The following frequency distribution represents the heights (in inches) of 80 randomly selected 5-year-old females.

(a) Use MINITAB or some other statistical software to construct a relative frequency histogram. Comment on the shape of the distribution. Draw a normal density curve on the relative frequency histogram.
(b) Do you think the normal density function accurately describes the heights of 5-year-old females? Why?
