The height of males 18 years and older in the USA can be assumed to be normally distributed, with mean 70 inches and standard deviation is 2 inches. a. (2 pt) Using the below normal curve, label the mean, and standard deviations ranging from 3 below to 3 above the mean (as is done in the text) and label the percentages as is done for the empirical rule. b. (3 pt) Using the empirical rule, what is the probability that a randomly selected US male is shorter than 74 inches? c.

`(3pt)`

Using the empirical rule, what height would be such that

`16%`

of all US males are shorter than that height?
