Question

25)

Given the linear correlation coefficient r and the sample size n, determine the critical value 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 = -0.568, n = 25

Select one:

a. Critical values: r = ±0.396, 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 = ±0.487, no significant linear correlation

Explanation / Answer

c. Critical values: r = ±0.487, significant linear correlation
