Display confidence and prediction intervals for Simple Regression (Options tab)

On the Options tab of the Simple Regression dialog box, specify whether you want to display the confidence interval or the prediction interval around the regression line on the fitted line plot.
Note

On the fitted line plot, the confidence and prediction intervals are displayed as dashed lines that identify the upper and lower limits of the intervals.

Confidence interval
Display the 95% confidence interval, which represents a range of likely values for the mean response.
Prediction interval
Display the 95% prediction interval, which represents a range of likely values for a single new observation. The prediction interval is always wider than the corresponding confidence interval because predicting a single response value is less certain than predicting the mean response value.
