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 Haum - Hw70, where Pm 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?
There is not a significant difference in mean weight loss between men and women
There is sufficient evidence that there is a difference
mean weight loss between men and women
There is sufficient evidence that, on average, men lose more weight than women
The proportion of men who lost weight is greater than the proportion of women
There is insufficient evidence that the proportion of men and women who lost weight is different.
