Assessing Normality Listed below are the recent salaries (in millions of dollars) of players on the San Antonio Spurs professional basketball team.

a. Do these salaries appear to come from a population that has a normal distribution? Why or why not?

b. Can the mean of this sample be treated as a value from a population having a normal distribution? Why or why not?

Step 1

**Note: **In this context, software usage is not mentioned. So, MINITAB software is used to test the normality assumption.

Step 2

**a.**

Procedure to obtain the histogram by using the MINITAB software is as follows:

- Choose
**Graph > Histogram**. - Choose
**Simple**, and then click**OK**. - In
**Graph variables**, enter the column of**Salaries**. - Click
**OK**.

Step 3

Procedure to obtain the normal quantile plot by using the MINITAB software is as follows:

- Choose
**Graph > Probability Plot**. - Choose
**Single**, and then click**OK**. - In
**Graph variables**, enter the column of**Salaries**. - In the graph dialog box, click
**Distribution**. - Clic...
