In a sample ofn = 20, the correlation between two variables is r = 0.7. Determine if this correlation is significant by calculating the t value and comparing it to the critical t-value in the table above. Do this for both .05 and .01 levels of significance. Ot = 2.92, significant at both .05 and .01 levels (two-tailed) Ot= 4.17, significant at both.05 and .01 levels (two-tailed) Ot= 2.77, significant at .05, but not at .01 level (two-tailed) Ot=4.38, significant at .05, but not at .01 level (two-tailed)
