This is the currently selected item. However a 95 confidence interval for the slope is 180 256. Df n - 2 101 - 2 99. Confidence Interval for Prediction of Slope 95 confidence interval for 1 would be. Confidence interval for slope. 1235 - Confidence Interval for Slope We can use the slope that was computed from our sample to construct a confidence interval for the population slope β 1.

Df n - 2 101 - 2 99. For two-sided confidence intervals this distance is sometimes called the precision -width. So if the slope estimate x 0 the upper bound will always be positive. 0054 3182 7850 1 0018 0090 We can be 95 confident that for each increase of 1 ml in alcohol the increase in time taken is between 0018 and 0090 mins. But the confidence interval provides the range of the slope values that we expect 95 of the times when the sample size is same. This confidence interval follows the same general form that we have been using.
