Procedure 14.2

Regression t-Interval Procedure

Purpose To find a confidence interval for the slope, β1, of the population regression line

Assumptions The four assumptions for regression inferences

Step 1: For a confidence level of 1 − α, use Table IV to find tα/2 with df = n − 2.

Step 2: The endpoints of the confidence interval for β1 are β1 ± tα/2 .se/√Sxx

Step 3: Interpret the confidence interval.
