Question

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 = 0.105, n = 15

Answer 1

Solution :

significance level of 0.05. r = 0.105, n = 15 , df = n -2 = 13

Critical value of r = 0.514

The given r does not represents a significant correlation.
