Hello Tutor,

Could you help me solving this problem along with some good explanation to understand the concept?

Q: A studyinvestigated the perception of corporate ethical values among individuals specializing in marketing. The following data shows the perception among three groups namely Marketing Managers Marketing research, and advertising.

Marketing manager	6	5	4	5	6	4
Marketing research	5	5	4	4	5	4
Advertising	6	7	6	5	6	6

The table value of F for df₁ = 2 and df₂ = 15 with 5% level of confidence is 3.68;

Do the above data indicate that the perceptions among the three groups are significantly different?
