Ans:

Correct options are:

This study is an experimental study.

The treatment was the number of cookies eaten.

Explanation:

The researcher has no control over the variables in an observational study,but in above case,we are able to assign subjects to different groups and also give treatment,so it is experimental study.

observational studies attempt to understand cause-and-effect relationships. However, unlike experiments, the researcher is not able to control (1) how subjects are assigned to groups and/or (2) which treatments each group receives.

An experiment is a method of applying treatments to a group and recording the effects. Remember, a good group experiment will have two basic elements: a control and a treatment.
