Option D
Step-by-step explanation:
In this experiment, It would have been scientific to compare the result of the experiment on the experimental group(taking the multivitamin) with the control group (Taking no medicine)

Answer:
The mean number of the children is 1.2
<em></em>
Step-by-step explanation:
Given
Children: 0, 1, 2, 1, 2
Required
Determine the Mean number
The mean of a set is calculated as follows;
![Mean = \frac{\sum x}{n}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B%5Csum%20x%7D%7Bn%7D)
Where x is the given set and n is the number of sets
In this case, n = 5 children
Hence;
![Mean = \frac{0 + 1 + 2 + 1 + 2}{5}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B0%20%2B%201%20%2B%202%20%2B%201%20%2B%202%7D%7B5%7D)
![Mean = \frac{6}{5}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B6%7D%7B5%7D)
![Mean = 1.2](https://tex.z-dn.net/?f=Mean%20%3D%201.2)
<em>Hence, the mean number of the children is 1.2</em>
