**Educational Website Text:** **Topic:** Using Confidence Intervals **Objective:** Learn how to calculate the margin of error and the sample proportion from a given confidence interval. --- **Instructions:** You are given a confidence interval: (0.651, 0.679). Use this interval to find: 1. The margin of error (E). 2. The sample proportion. **Formula for Margin of Error (E):** \[ E = \frac{\text{Upper Limit} - \text{Lower Limit}}{2} \] **Steps:** 1. Identify the lower and upper limits of the confidence interval. 2. Substitute these values into the margin of error formula. **Finding the Sample Proportion:** - The sample proportion is the midpoint of the confidence interval: \[ \text{Sample Proportion} = \frac{\text{Upper Limit} + \text{Lower Limit}}{2} \] **Input Field:** - **E = [ ]** (Type an integer or a decimal.) **Additional Resources:** - **Help Me Solve This**: Step-by-step guidance. - **View an Example**: See similar solved problems. - **Get More Help**: Access further explanations and resources. **Actions:** - Use the **Clear All** button to reset your entries. - Click **Check Answer** to validate your calculations. --- **End of Instructions**
