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 = 0.75, n = 9
Student Answer: Critical values: r = ±0.666, no significant linear correlation
Critical values: r = 0.666, no significant linear correlation
Critical values: r = -0.666, no significant linear correlation
Critical values: r = ±0.666, significant linear correlation
