Question

I used ANOVA Single Factor to calculate the p-value=0.08018. The option for the answer "between .05 and .10" is incorrect. It's saying that the correct answer is "Less than .01".

Chapter 13, Assignment #3:

The following data are from an experiment designed to investigate the perception of corporate ethical values among individuals who are in marketing. Three groups are considered: management, research and advertising (higher scores indicate higher ethical values).

5	6	7
4	5	6
5	5	5

p-value= 0.08018 (Hence your computation is correct). Since 0.01<0.05<p-value<0.1, the correct option is

0.05<p-value<0.1. Hence your answer is correct.

Note: "It's saying that the correct answer is "Less than .01"" is not correct option.
