Deciles by using normal distribution

This document provides examples of calculating deciles from a normal distribution. In example 1, it finds the 4th decile (144.9) for a normal distribution with a mean of 150 and standard deviation of 20. In example 2, it finds the 7th decile (107.8) for a normal distribution with a mean of 100 and standard deviation of 15. It shows the calculations using the normal distribution function and z-values from a standard normal distribution table.
