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

Answer 1

Answer:

12.6 years

Step-by-step explanation:

Once you have these written out you kinda just have to look for the middle one and in this that is 12.3 and 12.9 so you add them and then divide by 2. When you add them you get 25.2 and when you divide by 2 you get 12.6. So the median of this data set is 12.6.
