A correlation coefficient computed for n 18 and a 10 signif

A correlation coefficient computed for n = 18 and a 10% significance level is 0.692. Using a t-test for significance of the correlation coefficient, what is the largest critical value

A. +2.120

B.+2.101

C.+1.734

D.+1.746

Solution

Sol)

n=18

correlation coefficient =0.692

d.f =(n-2)=16

level=0.1

t critical value= 1.746
