Answer 1

Answer #1

here you first find critical value t at level of significance ; suppose here level of sigifcance is 0.05 and degree of freedom

=n-2=230-2=228

hence critical value t =tinv(0.05,228) =1.970 (excel formula is in bold)

therfore crtiical correlation coefficient =sqrt(t²/(t²+n-2)) =sqrt(1.970²/(1.970+230-2))=0.129

( please revert for any clarification required)
