Part I: Studies have shown how drinking alcohol can increase aggression. However, a psychologist is interested in whether the relationship between alcohol and aggression depends on the environment that the person is in. The psychologist recruits a sample of participants and randomly assigns them to either drink alcohol (drunk condition) or drink juice (sober condition). They also manipulate the context that the person is in by having half of each group watch either a boxing match or an opera show. Treatenvironment (boxing vs. opera) as your row factor andalcohol (drunk vs. sober) as your column factor. The data from this study are provided in the table below.

Boxing	Opera
Sober	Drunk	Sober	Drunk
5	10	3	5
6	11	2	5
3	10	1	6
5	13	3	5
6	11	6	4

Question: Find each of the cell means, the row marginal means (environment), the column marginal means (alcohol), and the grand mean (GM). Use the following table to organize your answers.
