If r = 0.84 and N = 5, the value of t obt for the test of the significance of r is _________.
A) 1.96
B) 2.40
C) 2.68
D) 3.46

Question

Quizplus · Accepted Answer

To find t obt for the test of significance of r, we first need to calculate the degrees of freedom (df) which is df = N-2 = 5-2 = 3. Using this df, we can look up the critical value of t in a t-table. For a two-tailed test with an alpha level of 0.05 (or 5%), the critical value of t with 3 degrees of freedom is 2.68. Therefore, the answer is choice C.
