A paired sample study has been conducted to determine whether two populations have equal means. Twenty paired samples were obtained with the following sample results: $\bar{d} = 12.45$; $s_d = 11.0$; $n = 20$ Based on these sample data and a significance level of 0.05, what conclusion should be made about the populations means?
