Final answer:
The correct interpretation of the map showing mean household income in Washington counties is that the area around Olympia has a higher average wealth compared to the area around Yakima.
Step-by-step explanation:
The student's question is regarding the interpretation of a map showing mean household income in Washington counties, specifically around the Olympia area. Given the options, the information on the map suggests that the area around Olympia has a certain level of average wealth in comparison to another area and not about income equality or employment rates.
Olympia, being the capital city of Washington, would likely have a different economic profile compared to areas like Yakima, which has different economic drivers and demographics. Therefore, the most relevant information we can discern from the map, without additional context on income equality, employment rates or population sizes, would be the relative average wealth between these identified areas.
The correct option to the student's question would then be the one indicating that the area around Olympia has a higher average wealth than the area around Yakima, assuming that the specified income ranges are accurate for these regions on the map.
