Given the Linear Correlation Coefficient R and the Sample Size $$\mathrm { r } = 0.803 , \mathrm { n } = 9$$

question 1

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.
- $$\mathrm { r } = 0.803 , \mathrm { n } = 9$$

• A) Critical values: \(r = - 0.666\), no significant linear correlation
• B) Critical values: \(\mathrm { r } = 0.666\), no significant linear correlation
• C) Critical values: \(r = \pm 0.666\), significant linear correlation
• D) Critical values: \(r = \pm 0.666\), no significant linear correlation
