The manager of an apartment complex ordered the air conditioners in the apartments to be replaced. The list shows how many years each air conditioner had been in service. 12.2, 13.7, 11.9, 13.4, 11.9, 12.3, 12.9, 11.8, 13.3, 13.6

Question:
What is the median number of years that an air conditioner had been in service?

The median is 12.6.

Explanation:

To find the median you list them from greatest to least then whatever number is in the middle is your median.

11.8, 11.9, 11.9, 12.2, 12.3, 12.9, 13.3, 13.4, 13.6, 13.7

So the middle two numbers are 12.9 and 12.3 so you would find the average by adding them together and dividing by 2.

12.3+12.9=25.2
25.2/2=12.6
