Step-by-step explanation:
To find the departments whose employees earn more than $2,100 on average, we can refer to the United States Department of Labor's Bureau of Labor Statistics. They provide data on the usual weekly earnings of full-time wage and salary workers in various departments. By looking at the data, we can determine which departments have average earnings above $2,100. This information can be found in Table 9 of the 2014 Annual Averages report.
For example, let's say the data shows that the average earnings in the Marketing department are $2,400. This means that employees in the Marketing department earn more than $2,100 on average. So, the Marketing department is one of the departments where employees earn more than $2,100 on average.
By analyzing the data in Table 9, you can identify all the departments that meet this criterion.
