Hypothesis Testing

**Hypothesis testing** is a statistical procedure that is used to test certain statements about a population on the basis of sample data.

There are many different hypothesis tests and although they all have their own nuances, the general procedure is the same for each one:

- State the hypotheses
- Set the criteria for a decision
- Collect the sample data and compute the test statistic
- Calculate the #p#-value
- Make a decision

In this chapter, you will learn how to employ a #Z#*-test* to test certain statements about a population mean #\mu#.

Z-test

A #\boldsymbol{Z}#-**test** is any statistical test for which the distribution of the test statistic is assumed to be (approximately) normally distributed.
