Final answer:
David's argument about the fairness of employee wages is flawed as it ignores the skewing effect of high wages on average salary calculations, and does not consider the potential distribution issues within departmental averages.
Step-by-step explanation:
The student is questioning the argument made by David, who suggests that there are no fairness issues with employee wages at their company. David's reasoning, however, may contain some flaws. When David mentions that the average salary of all the employees is over $50,000 and the number of departments with an average salary over $40,000 is greater than those under, he is overlooking key factors in wage fairness discussions. Option c) Focusing on the median wage rather than the mean could provide a clearer picture of employee compensation, as the use of the mean can be skewed by the high salaries at the top, not reflecting the majority's earnings. Additionally, option b) The disparity in departmental averages suggests potential salary distribution issues is valid, as varying departmental averages can reveal inequities within a company.
