As the manager of the human resources department at your firm, you are investigating the number of sick days employees took during the last calendar year. For employees in the marketing area, the average number of sick days is 4.8 with standard deviation 2.1; for those in the research and design (R&D), the mean is 5.2 with standard deviation 3.1. Compute and compare the coefficients of variation for each set of data.
