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 = 0.843, n = 5

Answer 1

using t-test, the test statistic ist=r √n−2 / √ 1−r2
t = 2.71at alpha of .05, assuming 2 tailed testcritical value is 3.182conclude it does not represent significant correlation
Also critical values for r+- .8783
