The correct inference that can be drawn from the dot plots is:

Online customers buy an average of four packs compared with walk-in customers, who buy an average of two packs.

This is because the dot plot for online customers shows a higher concentration of dots around the 4 and 5 marks, while the dot plot for walk-in customers shows a higher concentration of dots around the 1 and 2 marks.
