Hypothesis Testing on Multiple Populations
The Course Manager wants to use a new tutorial to teach the students about business ethics. As an experiment she randomly selected 15 students and at random assigned them to one of three groups which include either a PowerPoint presentation created by the faculty, Author Gen Presentation created by the faculty, or a renowned tutorial by the ABC Company. After completing their assigned tutorial, students are given a Business Ethics test. At.01 significance level, can she conclude that there is a difference between how well the different tutorials work for the students?
