Big Ideas: Technology can be used to accurately predict population percentages for intervals that do not lie exactly 1, 2 or 3 standard deviations from the mean. Prior to this lesson, students have learned to use the empirical rule and the normal distribution model to predict population percentages. In this lesson, students will not discover the limitations of the empirical model and will need to use technology to determine percentages. By linking this lesson to a real world application, students are also required to compare data and make inferences. Special Materials: Graphing calculator Spreadsheet program
