Suppose you just graduated with an accounting degree and are trying to choose an accounting firm to begin your career. You spent hours researching many firms and have narrowed your search down to three (i.e. Aguilar, Brown and Cheng). You have surveyed accountants to determine if the average incomes at each firm are equal between each of your top three choices. Obviously you want to join the firm with the highest average pay. Below are a sample of salaries (i.e. eight individuals from each firm) enabling you to test the hypothesis that the average pay (in thousands of $) is equal between employers. Use Fisher's LSD procedure (if necessary) to test whether there is a significant difference between any of the firms.
