Chapter 1  Interpreting Data in Normal Distributions
"The first lesson of this chapter leverages student knowledge of relative frequency histograms to introduce normal distributions... In the second lesson, students build their knowledge of normal distributions using the Empirical Rule for Normal Distributions... In the third lesson, students use a zscore table and a graphing calculator to determine the percent of data in given intervals that are bounded by noninteger multiples of the standard deviation from the mean. In the last lesson, students use their knowledge of probability and normal distributions to analyze scenarios and make decisions." Carnegie Textbook 
"This curve is kind of a big deal. "  Carnegie Textbook

Lesson 1.1  Normal Distributions
"This lesson introduces normal distributions. "  Carnegie Textbook Lesson 1.2  The Empirical Rule for Normal Distributions
"In this lesson, students use normal curves and relative frequency histograms of the cell phone battery scenario to build conceptual understanding of the Empirical Rule for Normal Distributions. The standard normal distribution is introduced. Students compare and contrast a boxandwhisker plot with a normal distribution."  Carnegie Textbook 
Lesson 1.3  ZScores and Percentiles
"Using the contexts of hybrid car gas mileage and teen texting, this lesson focuses on determining the percent of data below any given data value, above any given data value, and between any two data values of a normal distribution. "  Carnegie Textbook Lesson 1.4  Normal Distributions and Probability
"In this lesson, students will use their knowledge of normal distributions and probability to analyze situations and make informed decisions. The context of the scenarios are teen texting, pizza delivery times, and prizewinning tomatoes."  Carnegie Textbook
