Question
**Understanding the Area of Shaded Regions in Normal Distribution** The problem requires finding the area of the shaded region. The provided graph illustrates the distribution of IQ scores among adults, normally distributed with a mean (μ) of 100 and a standard deviation (σ) of 15. **Graph Explanation:** - The bell curve graph represents a normal distribution of IQ scores. - The shaded region falls between the values of 70 and 125 on the x-axis, indicating the range of scores we are interested in calculating the probability for. **Instructions:** 1. **Review the Normal Distribution:** - Mean (μ): 100 - Standard deviation (σ): 15 2. **Calculate the Area:** - The area of the shaded region corresponds to the probability of IQ scores falling between 70 and 125. 3. **Follow the Solution Steps:** - Utilize standard normal distribution tables or software for precise calculations. - Enter these values to find the cumulative probability. **Answer Prompt:** - Please provide the area of the shaded region, rounded to four decimal places. **Reference Links:** - Click to view [page 1 of the table](#). - Click to view [page 2 of the table](#). This detailed explanation guides understanding of how to approach solving for the shaded area using normal distribution principles.
