Yo can someone help me please with math

Answer:
First you need to know what a range in a data set is and ythe range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set. If a six-server rack includes 90 W, 98 W, 100 W, 102 W, 105 W and 110 W, the power consumption range is 110 W - 90 W = 20 W.
1. 5, 7, 8, 10, 11, 13, 14, 18, 27 so then do 27-5 to get 22 as your answer
2. 8
3. 16
I hope that this helpes you :)
