A social psychologist is interested in whether the type of music a college student is listening to will have any effect on the number of beers the student drinks.  Fifteen college students were randomly assigned to one of three listening conditions and each student's beer consumption was covertly recorded during trips to three different taverns that played the type of music to which the student was assigned. The data is shown in the following table. List each of the assumptions for performing an ANOVA and for each assumption evaluate whether the described study meets the assumption.
