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 $\alpha$
-$$\mathrm { n } = 45 , \alpha = 0.01$$
A) $r = 0.402$
B) $r = 0.378$
C) $\mathrm { r } = \pm 0.294$
D) $r = \pm 0.378$
