UMUC plans 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: 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 ( Click on link). Use Excel Data Analysis at a = 0.01 to decide which tutorial to use?

Keep the Excel file open for the next two questions. () A) F = 0.884b

A) F = 0.e84

B) F = 0.884

C) F = 0.834 > Fait 0.388

D) F = 0.834 > Fcrit 0.892

E) F = 0.834

F) F = 0.834

For a choice to be correct, each part of the choice must be correct. If two choices seem to be equally correct, choose the choice that does not depend on sample to sample variation.
