10.6 Margin of error for a predicted response. Refer to Example 10.10. What is the 95% margin of error of when x = 9.0? If you increased the sample size from n = 100 to n = 400, would you expect the 95% margin of error for the predicted response to be roughly twice a large, half as large, or the same for x = 9.0? Explain your answer.
