Supposing a spinner with 4 sides, the sample space is:
{H1, H2, H3, H4, T1, T2, T3, T4}
The sample space is the <u>set that contains all possible outcomes for an experiment</u>.
In this problem:
- For the coin, there are two possible outcomes: H or T.
- Supposing the spinner has 4 sides, there are four possible outcomes: 1, 2, 3, or 4.
Hence, the sample space is:
{H1, H2, H3, H4, T1, T2, T3, T4}

Answer:
Control Group.
Step-by-step explanation:
A control group, in research, is a group that is not experimented by the researchers in an experiment. A control group is the opposite of an experimental group, on which the independent variable is performed. In other words, an independent variable is held on 'control' in control group.
<u>In the given scenario, the experiment is being performed to test a new physical therapy. To do so, the researchers divided the group in three groups, in which, one group did not receive any treatment; the treatment is held on 'control' in this group.</u>
So, according to the definition provided, the group that did not receive the treatment will be called a control group, thus the correct answer.
