Pls answer number 3 pls! i don’t understand it!

number 3 is asking which region (Pacific Northwest, Midwest, southern, etc...) is least populated. this map says that each dot equates a certain amount of people. therefore, a section of the map with more dots will be more populated. so the east is definitely not right because there are so many dark blue dots clustered there. the center of the US (the south/North Dakota area mostly) in contrast has way fewer dots.
