Their results showed that, on average, men rated the statement at 3.45, with a standard deviation of 1.33. Women’s ratings averaged 3.04 and had a standard deviation of 1.39.
Researchers performed two separate one-sample t-tests using this data to test if the mean rating for each group was different from 4 (the midpoint). Here is their conclusion:
“Men and women thought that women would suffer more [negative] consequences as a result of excessive drinking; men's mean responses differed significantly from the midpoint, , as did
women's, .“
Use this information to answer the following questions:
t(110) = 25.50, p < .001
t(111) = 24.19, p < .001
