### Educational Website Content #### Interactive Normal Distribution Tool **Instructions:** You can adjust the shading on the normal distribution curve by selecting from the dropdown and dragging the arrows. This helps visualize different statistical probabilities. **Graph Explanation:** - The graph displays a normal distribution curve. - The x-axis ranges from -4 to 4, with a focus point at -1.5. - The area to the left of -1.5 is shaded in blue, indicating the probability or significance level for this section of the curve. **User Actions:** - **Shade:** Select "Left of a value" from the dropdown to highlight areas under the curve. - **Interactive Feature:** Click and drag the arrows along the x-axis to adjust the shaded region to various values. **Decision Making:** - A multiple-choice dropdown question asks for the correct decision regarding the shaded area. **Summary Statement:** - Another dropdown question asks for a summary related to the statistical analysis of the mean SAT completion time, focusing on if it has significantly changed from 2.6 hours. This tool is aimed at helping learners understand statistical concepts such as normal distribution, significance testing, and probability.
