Given the Linear Correlation Coefficient R and the Sample Size $\mathrm { r } = 0.71 , \mathrm { n } = 25$

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.
- $\mathrm { r } = 0.71 , \mathrm { n } = 25$

A) Critical values: $r = \pm 0.396$ , significant linear correlation
B) Critical values: $\mathrm { r } = \pm 0.487$ , no significant linear correlation
C) Critical values: $\mathrm { r } = \pm 0.487$ , significant linear correlation
D) Critical values: $r = \pm 0.396$ , no significant linear correlation
