ANOVA, pivot table, chi square test for independence

ANOVA:
 
NYU wants to use a new tutorial to teach the students about business ethics.  As an experiment the administrator randomly selected 15 students and randomly assigned them to one of three groups which include either a PowerPoint presentation created by the faculty, AuthorGen Presentation created by the faculty, or a well known tutorial by the ABC company.  After completing their assigned tutorial, the students are given a Business Ethics test.  At the .01 significance level, can NYU conclude that there is a difference between how well the different tutorials work for the students?
