**Interpreting Confidence and Prediction Intervals** *Two intervals are given, A and B, for the same value of the explanatory variable.* - **Interval A:** 17.7 to 21.1 - **Interval B:** 15.1 to 23.7 **Questions:** (a) Which interval is the confidence interval for the mean response? - **Answer:** [Dropdown selection] Which interval is the prediction interval for the response? - **Answer:** [Dropdown selection] (b) What is the predicted value of the response variable for this value of the explanatory variable? - **Enter the exact answer:** The predicted value is [Input box]. --- **Explanation:** In this exercise, two intervals are provided to evaluate which serves as the confidence interval for the mean response and which is the prediction interval for the response. Typically, a confidence interval for the mean response is narrower than the prediction interval due to the additional variability accounted for in predicting individual responses. This exercise helps reinforce understanding of statistical concepts related to intervals, essential for analyzing data and drawing conclusions based on variability and uncertainty.
