Question

Quizplus · Accepted Answer

The standardized test statistic $t$ can be calculated using the formula $t = \frac{r\sqrt{n-2}}{\sqrt{1-r^2}}$, where $r$ is the sample correlation coefficient, and $n$ is the sample size. Substituting $r = -0.765$ and $n = 22$, we get $t = \frac{-0.765\sqrt{22-2}}{\sqrt{1-(-0.765)^2}} \approx -5.312$.
