unit: Inference for Quantitative Data: Slopes topic: Confidence Intervals for the Slope of a Regression Model learning objective: Identify an appropriate confidence‑interval procedure for the slope of a regression model. essential knowledge: The sample regression line estimates the population regression line. The sampling distribution of the slope has a mean equal to the population slope and a specific standard deviation.
