ANOVA An experiment was conducted to determine if motivational techniques in management significantly impacted 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 transformational motivation technique, and then a control group with no new technique used.  Stress levels were self-reported by the employees as shown below.  Use alpha = 0.05 Transformational Transactional Control 0 2 6 7 5 5 3 3 8 5 0 9 2 1 5   What is your null hypothesis? What is your alternative hypothesis?   After running the single factor analysis of variance 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? Yes No Do you reject or accept the null hypothesis? Reject                   Accept
