Description
In Lesson 10, students first learn how to calculate 𝑧-scores and are then shown how to use 𝑧-scores and a graphing calculator to find normal probabilities. Students are then introduced to the process of calculating normal probabilities using tables of standard normal curve areas. In this lesson, students calculate normal probabilities using tables and spreadsheets. They also learn how to use a graphing calculator to find normal probabilities directly (without using 𝑧-scores) and are introduced to the idea of fitting a normal curve to a data distribution that seems to be approximately normal.
