Answer:

D

Step-by-step explanation:

the median is the middle value of a data set in ascending order

If there is not an exact middle then it is the average of the values on either side of the middle

Arrange data in ascending order

15, 17, 19, 21, 23, 25, 26, 28, 28, 30

the middle is between 23 and 25 , hence

median = [tex]\frac{23+25}{2}[/tex] = [tex]\frac{48}{2}[/tex] = 24

Answer:

The answer id D) 24

Step-by-step explanation:

To find the median, first put all of the value into number order.

15, 17, 19, 21, 23, 25, 26, 28, 28, 30

Then choose the number (or numbers) that are in the middle.

15, 17, 19, 21, 23, 25, 26, 28, 28, 30

Since there is an even number, we have to take an average of the two numbers in the middle to get the median. The average of 23 and 25 is 24.
