based on a study of the heights of the u.s male population between the age of 20 to 29 and between the years 2003 to 2006 you assume that the height of U.S. males in this age category and time period is normally distributed. Their mean height is 177.6 cm and the population standard deviation is 9.7 cm.

a) what is the friction of this population over 6ft tall (182.88 cm)

b) what fraction of the population are between 5 ft 4 in (162.56 cm) and 6 ft (182.88 cm) tall?

c) what fraction of population are between 5 ft (152.4 cm) and 5 ft 4 in (162.56 cm) tall?
