Question
Assume that you have a data set consisting of the age of all New York City police officers. Examination of a histogram and normal quantile plot are two different ways to assess the normality of that data set. Identify a third way.
Step 1
The range rule of thumb is a simple statistical rule stating that the range (the difference between the maximum and minimum values in a data set) is approximately four times the standard deviation. Show more…

Identify two different characteristics of a normal quantile plot, where each characteristic would lead to the conclusion that the data are not from a normally distributed population.
Normal Probability Distributions
Assessing Normality
Examine the normal quantile plot and determine whether the sample data appear to be from a population with a normal distribution. The normal quantile plot represents the ages of presidents of the United States at the times of their inaugurations. The data are from Data Set 15 "Presidents" in Appendix $\underline{B}$.
Use the data from the indicated exercise in this section. Use a $\pi$ - $83 / 84$ Plus calculator or computer software (such as STATDISK, Minitab, or Excel) to generate a normal quantile plot. Then determine whether the data come from a normally. distributed population. Exercise 9
