The height of 20- to 29-year-old males has a mean of 70.4" and a standard deviation of 3". The height of 20- to 29-year-old females has a mean of 65.1" and a standard deviation of 2.6". A random sample of 500 20- to 29-year-old people from the Midwest and 350 20- to 29-year-old people from the Northeast found that 82 from the Midwest and 65 from the Northeast did not meet the height requirement to work as a flight attendant.
