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. Plugging in the given values: $t = \frac{0.823\sqrt{10-2}}{\sqrt{1-0.823^2}} \approx 4.098$.
