Quizplus · Accepted Answer

For a two-tailed test with n = 10 pairs of data and $\alpha = 0.05$, the critical value for the correlation coefficient is $\pm 0.648$ based on the t-distribution table for 8 degrees of freedom (n-2).

Find the Critical Value n=10,α=0.05\mathrm { n } = 10 , \alpha = 0.05n=10,α=0.05
