Refer to Exercise 13.123. Is there more variation in the amount of debt of the self-employed than for employees (DEBT)?

In exercise 13.123

The financial rewards for self-employment can be considerable. The downside may be that one works long hours accruing debts with little or no financial return. As a result we theorize that the variance in compensation will be greater for the self-employed (OCCAT1: 1 = work for someone else, 2 = self-employed/partnership). Conduct a test to determine if the variation in income for the self-employed is greater than that of employees (INCOME).
