Answer:
Letter B is the correct answer. Median is 4 and IQR is 5.
Step-by-step explanation:
Jason : 8,8,11,13,14,14,15,18,21,22,22,27,27,28,30
median = 18
IQR = 27 - 13 = 14
Ed : 7,12,12,15,19,21,21,21,21,22,23,23,26,27,27
median = 21
IQR = 23 - 15 = 8
Their medians cannot be compared based on their IQR's are 6 points apart

To better understand the question we need to properly format the expression
as we can see we have three brackets, we can proceed by first opening the first two brackets, we have.
we then continue by collecting like terms
we then solve for the remaining two brackets
from the two brackets we obtained each, we now have to multiply both terms together and solve we have
collecting and summing all like terms we have
