Which statements are correct?

Answer:
- The number of bags sold at North and South varied about the same amount
- The number of bags sold at West varied less than did the number sold at South
Step-by-step explanation:
If we look at the variation column, we see that the number of bags sold at North and South varied about the same amount, 6.9 and 6.7, which is pretty close to each other.
Still looking at that table, we see that the number of bags sold at West varied less than did the number sold at South, 3.1 versus 6.9, that's a huge difference.
I hope this helps you understand more the variations shown in the table.
