A5 The model below explains CEO salary (salary) expressed in thousands of pounds as a function of a firm’s sales in million pounds (sales), the return on a firm’s equity (roe), and the industry in which the firm is operating. There are two industries in the sample, services and consumer goods. These industries are captured respectively by two dummy variables, service and goods. The regression based on a sample of 209 firms is as follows: salary = 4.5 + 0.27sales + 0.015roe – 0.08service (0.24) (0.03) (0.05) (0. 05) R-squared = 0.35 SSR(Residual Sum of Squares) = 42.9 Implement an F-test for whether the determinants of CEO salaries differ significantly between service and consumer goods industries.
