The corresponding cumulative distribution function question is, "What's the probability you'll be shorter than 5'4"?" The figure above showed two normal distributions. You can now see these are ...

NORMSINV is an Excel function used along with normal distributions. It allows you to conduct calculations faster and with more precision than by doing them by hand. Further, you can use NORMDIST ...

The PROBMED function computes the probability that the sample median is less than or equal to x for a sample of n independent, standard normal random variables (mean 0, variance 1).
