Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your
finding to state whether or not the given r represents a significant linear correlation. Use a significance level of
0.05.
r = 0.543, n = 25
A) Critical values: r = +0.487, no significant linear correlation
B) Critical values: r = +0.396, no significant linear correlation
C) Critical values: r = +0.487, significant linear correlation
D) Critical values: r = +0.396, significant linear correlation

The critical value of r is mathematically given as r = +0.487, with no significant linear correlation. Option A.

What are the critical values of r?

Question Parameters

r = -0.868

n = 5

df = 5 - 2

df = 3

[tex]\alpha / 2 =0.025[/tex]

Critical values [tex]r= \pm 0.878[/tex]

Generally, there exists no linear correlation between the Critical values

as r=0.878

In conclusion,  Critical values: r = +0.487, no significant linear correlation
