In the medical cost example, which years are cited for costs?

• A. 2003-2005
• B. 2005-2007
• C. 2004-2006
• D. 2002-2004

Answer: (C)

The main idea is to identify the time period actually used for presenting the medical cost data. In this example, the costs are shown for three consecutive years: 2004, 2005, and 2006. All cost calculations and discussion are based on this window, so those are the years cited for costs. Other ranges would not match the data presented (they would omit one of the shown years or include a year not shown). So the costs correspond to 2004-2006.
