Computer regression output

Read the table in two parts. The Predictor column names the rows, with Constant carrying the y-intercept and the explanatory variable carrying the slope, both in the Coef column, while SE Coef, T, and P give the standard error and the slope test for that row. Below the table, s is the standard deviation of the residuals and R-Sq is $r^2$, so you recover the correlation as $r = \pm\sqrt{\text{R-Sq}}$ and take the sign from the slope: R-Sq of 81.0% with a slope of $-1.4$ gives $r = -0.9$. The T and P columns belong to inference for regression slopes, which the AP Statistics course effective Fall 2026 no longer tests. The whole table is textbook and college material; the Fall 2026 AP course gets $a$, $b$, $r$, and $r^2$ from technology instead.
