The particular industry group (e.g., banking, chemicals) a company belongs to is coded in the variable indgrp. Executive compensation is measured by two variables (comp for salary and bonus and also def for deferred compensation). Combining these two variables, comp and def, would be a measure of total compensation. The question: Does total compensation differ among industries #3, #8, #11, #20, and #24? Please exclude the other industries from the analysis for this question. Please note: Although this problem requires you to form the total compensation variable, if you do not know how to do this just use comp instead of total compensation.
