In a two-tailed test for correlation at α = .05, a sample correlation coefficient r = 0.42 with n = 25 is significantly different than zero.

True or False

Solutions

Expert Solution

True

We have given,

Two tailed test,

a sample correlation coefficient r = 0.42 with n = 25

Degree of freedom =n-2 = 25- 2 = 23

r critical values

|r| = 0.42 > 0.396

Therefore, we reject H0 at
