Refer to the Mega-Stat/Excel Output for the Wilcoxon Signed Rank

Multiple Choice

Refer to the Mega-Stat/Excel output for the Wilcoxon signed rank test given in the table below. At a significance level of .01,which one of the following statements is correct regarding the following null hypothesis? H₀: 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 failed to 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 failed to 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 failed to 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.
