Confidence interval

The two rightmost columns of the regression table above (lower_ci and upper_ci) correspond to the endpoints of the 95% confidence interval for the population slope β1\beta_1. Recall our analogy “nets are to fish what confidence intervals are to population parameters” from the Understanding Confidence Intervals lesson. The resulting 95% confidence interval for β1\beta_1 ...
