Refer to the MegaStat/Excel Output for the Wilcoxon Signed Ranks

Multiple Choice

Refer to the MegaStat/Excel output for the Wilcoxon signed ranks test given in the table below. At a significance level of .01,which one of the following rejection point conditions is correct regarding the null hypothesis,H₀: D₁ and D₂ are identical probability distributions,and the alternative hypothesis of H_a: D₁ is shifted to the left of D₂.

A) We reject H₀ and conclude there is not sufficient evidence that the probability distribution of population 1 is shifted to the left of the probability distribution of population 2.
B) We cannot reject H₀ and conclude there is not sufficient evidence that the probability distribution of population 1 is shifted to the left of the probability distribution of population 2.
C) We reject H₀ and conclude there is very strong evidence that the probability distribution of population 1 is shifted to the left of the probability distribution of population 2.
D) We do not reject H₀ and conclude there is very strong evidence that the probability distribution of population 1 is shifted to the left or to the right of the probability distribution of population 2.
E) We do not reject H₀ and conclude there is very strong evidence that the probability distribution of population 1 is identical to the probability distribution of population 2.
