Answer:
Concept & Calculation of Range .
Step-by-step explanation:
11 , 13 , 14 , 14 , 15, 17 , 19 , 20
Even numbers greater than 11 = 14 , 14 , 20
Range = Highest Value - Lowest Value = 20 - 14 = 6
Entire data range = 20 - 11 = 9
Range of all numbers greater than 11 (ie 13 , 14 , 14 , 15, 17 , 19 , 20) = 20 - 13 = 7
