Now that we have studied the mean and standard deviation, let’s apply them to find probability using a distribution called the normal curve. Click here to open the lesson.

For the activities and future assignments in the module, you will need a Standard Normal Distribution Table, or Z-table.

You can also use your TI-84 graphing calculator to find normal distribution probability, rather than using the Z –table. Click here for instructions and examples using your calculator.
