Answer:
19
Step-by-step explanation:
First, you should arrange the data in ascending to descending to find the median.
12, 14, 15, 16, 17, 19, 21, 26, 26, 27, 28
Now let us use the given formula to find the median.
[tex]\sf \dfrac{n+1}{2} =--^t^h data[/tex]
Here,
n → the number of elements
Let us find it now.
[tex]\sf Median= \dfrac{n+1}{2}\\\\\sf Median=\dfrac{11+1}{2} =6^t^h data\\\\Median=19[/tex]
