Given the linear correlation coefficient r and the sample, Ask an Expert

Statistics

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 = 0.399, n = 25

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

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

Critical values: r = ±0.396, significant linear correlation

Critical values: r = ±0.487, significant linear correlation
