ANSWER
A. 25
Step-by-step explanation
We want to find the median of the data set given.
The first step is to arrange the data in numerical order, from least to greatest. That is already done from the question.
The median of a data set is the value that is at the middle of the data set.
Since there are 7 values in the data set, the median will therefore be the fourth value.
Therefore, the median is 25 (option A)
