Whether the given statement represents the survey, an observational study or an experiment.

Answer to Problem 11SGR
The statement is experimental study.
Explanation of Solution
Given:
Find 100 people and randomly split them into two equal groups.
One group eats a specific diet while the other group does not.
Considering the situation as “Find 100 people and randomly splitting it into the two groups.
One group is eating the specific diet and the other one is not.
The observational study states that the study in which researcher does not assign treatments to any subjects.
An experimental study states that the study where researcher assigns treatments to the subjects.
There are two groups, control group and the treatment group.
The control group is given placebo and treatment group is given treatment.
From the given situation, one group is assigned a specific diet while other will not
Which states that the one group is assigned treatment
Therefore, the given situation is an experimental study.
