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:
[tex]Median=7[/tex]
The upper quartile is:
9, 10, 12, 24
thus, [tex]LQ=\frac{10+12}{2}=\frac{22}{2}=11[/tex]
The lower quartile is:
2, 2, 4, 7
thus, [tex]LQ=\frac{2+4}{2}=3[/tex]
The highest value of the given data set is 24 and the lowest value is 2.
Therefore, option D is correct.
