An experiment was conducted to test the effect of a new dietary supplement for weight loss. Ten men and ten women were given the supplement daily for a month; then the amount of weight each person lost was determined. A significance test was conducted at the a = 0.05 level for the mean difference in the number of pounds lost between men and women. The test resulted in t = 2.178 and p = 0.03. If the alternative hypothesis in question was Ha: Mm - Hw 0, where um equals the mean number of pounds lost by men and Hw equals the mean number of pounds lost by women, what conclusion can be drawn?
