An experiment was conducted to determine if motivational techniques in management significantly affected employee stress levels compared to no intervention.  An employee survey was given to three groups: one group under a manager who started using a transformational motivation technique, one group under a manager who began using a transactional motivation technique, and then a control group with no new technique used.  Stress levels were self-reported by the employees on 10-point Likert scales (0 - no stress, 1- little stress, 9 - very high stress). The results are shown below.  Use alpha = 0.05.

1. After running the single factor analysis of variance (ANOVA) on the data, what is the p-value for between groups? Using the 95% significance level, is there a significance difference in stress levels between the three groups? Explain.

Question: I am not sure what else to explain for this?

2. From the results in #1, what decisions could be made by management? Discuss changes management should put in place based on your hypothesis test results.
