For the set {-12,-12,-4,8,16,20}, would each measure be affected if the value of 4 were included. a mode • yes • no b median • yes • no c mean • yes • no d range •yes •no

The mode would not be affected because there is no other value of 4, so -12 is still the mode.

The median would be affected because the median will be 4, rather then 2. 

The mean would change from 8/3 to 20/7

The range would not be affected because 4 would not be the greatest or the least number

Igot the answer of 15.8 years.
