Suggested approaches

This is a whole class task with opportunity for group discussion, as it starts with a problem. There is individual practice for determining probabilities/areas under a Normal distribution. As well as using tables for determining areas under a Normal distribution, you may wish to use calculators with built-in values.

+
Resources/documentation

There is a PowerPoint presentation and interactive whiteboard resources.

+
Relevant digital technologies

You could introduce the use of calculators with appropriate statistical functionality to determine areas under the Normal distribution.

+
Possible extensions
