Question

According to a recent report from the U.S. National Center for Health Statistics, females between 25 and 34 years of age have a bell-shaped distribution for height, with mean of 65 inches and standard deviation of 3.5 inches.
a. Give an interval within which about 95% of the heights fall.
b. What is the height for a female who is 3 standard deviations below the mean? Would this be a rather unusual height? Why?
