question 40

Multiple Choice

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.

• A) Critical values: \(r = \pm 0.217\), no significant linear correlation
• B) Critical values: \(r = 0.217\), significant linear correlation
• C) Critical values: \(r = \pm 0.207\), no significant linear correlation
• D) Critical values: \(\mathrm { r } = \pm 0.207\), significant linear correlation
