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 = 0.353, n = 15

A. Critical values: r = ±0.532, no significant linear correlation

B. Critical values: r = ±0.514, significant linear correlation

C. Critical values: r = ±0.514, no significant linear correlation

D. Critical values: r = 0.514, no significant linear correlation
