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 $r = 0.321$ and $n = 30$ into the formula gives $t = \frac{0.321\sqrt{30-2}}{\sqrt{1-0.321^2}} \approx 1.793$.
