The average height of women in the U.S. is 64 inches and the standard deviation is 2.4 inches. Assuming a Gaussian distribution, what fraction of women in the U.S. have a height greater than 68 inches?
Find the z-score: z = (score - average) / standard deviation
---> z = (68 - 64) / 2.4 ---> z = 1.6667
Finding normalcdf(1.6667, 100) = 0.04775 ---> 0.048
