Answer:
D
Step-by-step explanation:
You have to solve the compound inequality 
The absolute value
means the distance from the number b to the origin. Thus, the inequlity
has as solutions all numbers b that are at the distance from the origin greater than 6.
So, 
To find the median cancel out numbers on both sides, until one is left in the middle and if there are two in the middle add them up and divide by two.
So in this case the median is
53+78
131 / 2
65.5
