question 127

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.
- $r = 0.981 , n = 25$

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