Respuesta :

The correct answers are:

The number of cavities each person has; and observational study.

Explanation:

Quantitative data is data that can be described using numbers.  The only one listed that can be described with numbers is the number of cavities each person has.

Observational studies are ones in which a researcher observes but does not interfere.  Walking the cafeteria and seeing who has what type of lunch is a method of observation, so this is an observational study.
