5. In a research we use the pathmodel as sketched below: 21 32 31 The researcher conducts a Sobel test. She uses an online test on the internet. Below you find the output of this test. Input: Test statistic Std. Error p-value 0.13 0.003 0.000 Sobel test 3.923 0.10 3.89 0.003 0.000 Aroian test 0.02 3.95 0.003 The conclusion based on this output is that (use a 0.05) A. The direct effect significantly differs from 0 B. The direct effect does not differ significantly from o C. The indirect effect differs significantly from 0 D. The indirect effect does not differ significantly from 0

Explanation / Answer

Answer: Option C is correct

Reason: The Sobel test is testing the effect of the indirect path (from X1 through X2 to X3) to see if it's statistically significant. Its a null hypothesis significance test where the null hypothesis is that the indirect effect is 0. In this case, p-value of Sobel test is less than 0.05 so we reject null hypothesis. This means that there is sufficient evidence to support the claim that indirect effect differs significantly from 0
