Quizplus · Accepted Answer

For a two-tailed test with $n = 20$ pairs and $\alpha = 0.01$, the degrees of freedom (df) would be $n - 1 = 19$. Looking up the critical value in a t-distribution table or using a calculator for a two-tailed test with $\alpha = 0.01$ and 19 degrees of freedom, the critical value is approximately $\pm 0.570$.
