A random sample of 20 observations was made on the diameter of spot welds and the corresponding weld shear strength. Given that r = 0.75, what are the critical values if we want to test the hypothesis that
Ho: p = 0 versus H₁: p≠0, use a = 0.02.
Let 10.01:19 = 2.539, 10.01.18 = 2.552, 10.02.19 = 2.205, 10.02,18 = 2.214.
