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 0.767, n 25 = = A. Critical values: r 0.487, no significant linear correlation = ± B. Critical values: r 0.487, significant linear correlation = ± C. Critical values: r 0.396, significant linear correlation = ± D. Critical values: r 0.396, no significant linear correlation = ±
