Answer:
(D)
Step-by-step explanation:
The given data set is:
10, 12, 2, 4, 24, 2, 7, 7, 9
Firstly arrange the given data set in ascending order, we get
2, 2, 4, 7, 7, 9, 10, 12, 24
Now, the median of the above given data set is:
![Median=7](https://tex.z-dn.net/?f=Median%3D7)
The upper quartile is:
9, 10, 12, 24
thus, ![LQ=\frac{10+12}{2}=\frac{22}{2}=11](https://tex.z-dn.net/?f=LQ%3D%5Cfrac%7B10%2B12%7D%7B2%7D%3D%5Cfrac%7B22%7D%7B2%7D%3D11)
The lower quartile is:
2, 2, 4, 7
thus, ![LQ=\frac{2+4}{2}=3](https://tex.z-dn.net/?f=LQ%3D%5Cfrac%7B2%2B4%7D%7B2%7D%3D3)
The highest value of the given data set is 24 and the lowest value is 2.
Therefore, option D is correct.
