Question

The heights of young women are approximately normally distributed with a mean of 64.5 inches and a standard deviation of 2.5 inches. Determine the following:
what percent of young women would be acceptable as members if being a
member required a height of 70 inches or more?
For the population of young women determine the heights of the shortest 8%.
Diagrams required.

Answer 1

You need a z- score

70 - 64.5 divided by 2.5

Once you get the z-score, use a calculator or normal table to find the probability to the right of that z-score.
