Predicting Population Percentages Using a Graphing Calculator

This lesson teaches how to predict population percentages using a graphing calculator. It reviews the normal model, emphasizing the need to check data distribution before applying it. The empirical rule is explained, highlighting its limitations. A practical example using milk jugs demonstrates how to use a graphing calculator to find percentages under a normal distribution. The lesson also covers different methods for determining probabilities and provides detailed instructions for using a graphing calculator's statistics functions.
