B. Mean will decrease, but median will stay the same
The mean will decrease because 20 is less than every other value in the data set, hence the average will go down
The median will stay the same because add a seventh term with make the left 60 the median, before you added the 20, both 60's were in the middle, and the average of them was 60.
