Suppose you will perform a test to determine whether there is sufficient evidence to support a claim of a linear
correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance
level $\alpha$
-$$n = 11 , \alpha = 0.05$$
A) $\mathrm { r } = \pm 0.735$
B) $r = 0.632$
C) $r = 0.602$
D) $r = \pm 0.602$

Quizplus · Accepted Answer

With n=11 and $\alpha=0.05$, the critical values of r are $\pm 0.602$. This can be calculated using a table or a calculator. Option A is incorrect as it gives the critical value for n=10 instead of n=11. Option B and C are incorrect as they give a single value of r instead of a range of critical values.
