A study was conducted to determine whether there is a significant difference in the population mean for two groups with a sample size of n = 10 for each group. The results from the Wilcoxon Signed-Ranks Test resulted in a T-value of 15 and a p-value of 0.03. What conclusion can we make about the population means of the two groups?
