After complaints about gender discrimination regarding bonus incentive pay, a large multinational firm collected data on bonuses awarded during the previous year (% of base pay). Human Resources (HR) randomly sampled male and female managers from three different levels: senior, middle, and supervisory. The two-way ANOVA results are presented here.
a) Is this an experiment or an observational study?
b) State the hypotheses.
c) Given the small P-value associated with the gender and that the mean annual bonus percent for females is 12.5% compared to 14.5% for males, HR concludes that gender discrimination exists. Do you agree? Explain.
