Certainly! Here is the transcription and explanation for an educational website: --- ### Understanding the Area Under the Normal Distribution The following figure illustrates the normal distribution with the proportion of the area under the normal curve contained within one, two, and three standard deviations from the mean. - **0.13%** of the area is located beyond three standard deviations from the mean on either side of the curve. - **2.16%** is located between two and three standard deviations. - **13.59%** is between one and two standard deviations. - **34.13%** of the data lies between the mean and one standard deviation above or below it. The normal distribution is symmetric around the mean (\(\mu\)). ![Area Under Normal Distribution Graph](Image) \ *Figure: Normal Distribution Curve* --- #### Using the Figure for Analysis This graph is essential in helping you understand data distribution and standard deviation in statistical analysis. Below are some key questions and situations where this understanding is crucial. The **National Assessment of Educational Progress (NAEP)** is an important measure of student proficiency across various subjects, using samples from grades 4, 8, and 12. In **2002**, female students had a mean reading score of **269** with a standard deviation of **33**. Assuming a normal distribution, we can predict scores around the mean: 1. **Score Analysis Example** - A score of **170** is ________ standard deviations below the mean. - A score of **368** is ________ standard deviations above the mean. - Calculating these will inform us of the percentage of students scoring between certain ranges. Understanding and applying these concepts can aid in interpreting assessments like NAEP efficiently. ---

**Complete: Chapter 6 Problem Set** ### Figure Explanation The figure is a bell curve representing a normal distribution. The distribution is centered at the mean (μ) and is divided into segments by standard deviations (σ) from the mean. Each segment indicates the percentage of data that falls within those ranges: - **-3σ to -2σ**: 2.15% - **-2σ to -1σ**: 13.59% - **-1σ to 0**: 34.13% - **0 to +1σ**: 34.13% - **+1σ to +2σ**: 13.59% - **+2σ to +3σ**: 2.15% - **Beyond ±3σ**: 0.13% on each tail --- ### Text Content Use the figure to help you answer the following questions. The National Assessment of Educational Progress (NAEP) is a nationwide assessment of students' proficiency in nine subjects: mathematics, reading, writing, science, the arts, civics, economics, geography, and US history. The main NAEP assessments are conducted annually on samples of students from grades 4, 8, and 12. In 2002, the reading scores for female students had a mean of 269 with a standard deviation of 33. Assume that these scores are normally distributed with the given mean and standard deviation. A score of 170 is __________ below the mean, while a score of 368 is __________ above the mean. This means that the percentage of female students with scores between 170 and 368 is __________. A score of 302 is __________ above the mean. As a result, the percentage of female students with scores below 302 is __________. You can infer that 97.72% of the female students have scores above __________.
