As there is a growing concern about alcohol-related problems on college campuses, a team of researchers was interested in studying students' perceptions about alcohol consumption-more specifically, in how students define a "drink" (White et al, 2004) . These researchers were interested in seeing whether the size of a cup influences how much beer students will pour into the cup. In their study students poured what they believed were 12 ounces of beer into one of three cups of different sizes (16, 24, or 32 ounces) . They hypothesized that the larger the cup, the more beer students would pour. The results of their analyses are presented below:
You decide to conduct the analytical comparison of 16 oz vs. 24 oz.
In conducting this analytical comparison, how should the null and alternative hypotheses be stated?

The null hypothesis (H₀) should state that there is no difference in the mean amount of beer poured between the 16 oz and 24 oz cups, which is represented as μ16 oz = μ24 oz. The alternative hypothesis (H₁) should state that there is a difference in the mean amount of beer poured between the two cup sizes, which is represented as μ16 oz ≠ μ24 oz.
