critical values

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, significant linear correlation O B. Critical values: r= +0.396, no significant linear correlation O C. Critical values: r= +0.487, no significant linear correlation O D. Critical values: r = +0.396, significant linear correlation
