2

Step-by-step explanation:

is the center

Step-by-step explanation:

There are lots of ways we can think about the typical number of cavities.

The most patients had 0 cavities.  

If we split the cavities evenly, each patient would have 2 or 3 cavities.  

If we put our dot plot on a balance scale, it would balance when the pivot was between 2 and 3 cavities.

The scale would tip if, for example, we put the pivot at 5 cavities.

There are 8 patients with 2 cavities each. About half of the rest of the patients have fewer than 2 cavities and about half have more than 2 cavities.

Of the choices, it is reasonable to say that a patient typically had about 2 cavities.
