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 = 0.812, n = 9 O Critical values: r = 0.666, significant linear correlation O Critical values: r = 0.666, no significant linear correlation O Critical values: r = 0.666, no significant linear correlation Critical value
