Question: The Course Manager for AMBA 601 wants to use a new tutorial to teach the students about business ethics. As an experiment she 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 .05 significance level, can she conclude that there is a difference between how well the different tutorials work for the students?
