6.19 Human Heights Human heights are one of many biological random variables that can be modeled by the normal distribution. Assume the heights of men have a mean of 69 inches with a standard deviation of 3.5 inches. a. What proportion of all men will be taller than 6'0"? (HINT: Convert the measurements to inches.) b. What is the probability that a randomly selected man will be between 5'8" and 6'1" tall? c. President George W. Bush is 5'11" tall. Is this an unusual height? d. Of the 42 presidents elected from 1789 through 2006, 18 were 6'0" or taller.' Would you consider this to be unusual, given the proportion found in part a?
