Statistical Inferences About β1

Key Takeaways

The parameter $β_1$ , the slope of the population regression line, is of primary interest because it describes the average change in $y$ with respect to unit increase in $x$ .
The statistic $\hat{\beta}_{1}$ , the slope of the least squares regression line, is a point estimate of $β_1$ . Confidence intervals for $β_1$ can be computed using a formula.
Hypotheses regarding $β_1$ are tested using the same five-step procedures introduced in Chapter 8 "Testing Hypotheses".
