Refer to the MegaStat/Excel output for the Wilcoxon rank sum test given in the table below. At a significance level of .05, which one of the following statements is correct regarding the following null hypothesis? H₀: D₁ and D₂ are identical probability distributions. A) We reject H₀ and conclude there is very strong evidence that the median value of the first sample significantly differs from the median value of the second sample. B) We reject H₀ and conclude there is very strong evidence that the median value of the first sample is significantly less than the median value of the second sample. C) We do not reject H₀ and conclude there is not sufficient evidence that the median value of the first sample is significantly less than the median value of the second sample. D) We do not reject H₀ and conclude there is insufficient evidence to conclude that the median value of the first sample is not significantly different from the median value of the second sample. E) We do not reject H₀ and conclude there is very strong evidence that the median value of the first sample is significantly greater than the median value of the second sample.

Since the p-value (0.0037) is less than the significance level of .05, we reject H₀and conclude there is very strong evidence that the median value of the first sample significantly differs from the median value of the second sample.
