Question

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 then to one of three groups: a PowerPoint presentation created by the faculty, AuthorGen Presentation created by the faculty, or a well known tutorial by ABC company. After completing their assigned tutorial, the students are given a Business Ethics Test. Use Excel Data Analysis at (x = 0.01 to decide which tutorial to use?

	PowerPoint Tutorial	AuthorGen Tutorial	ABC Tutorial
	68	79	75
	85	86	83
	91	82	78
	87	92	86
	88	91	81

A) F = 0.834 > Fcrit 0.692

B) F = 0.684 < Fcrit 3.885

C) F = 0.684 < Fcrit 6.927

D) F = 0.834 > Fcrit 0.388

E) F = 0.834 < Fcrit 6.927

F) F = 0.834 < Fcrit 3.885

Answer 1

The statistic software output for this problem is:

Test statistics = 0.834

F _2,12,0.01 = 6.927

Critical value = 6.927

E) F = 0.834 < Fcrit 6.927
