Work on Both sides of the equation by doing the same thing on both sides. This will get your answer.
13, 17, 15, 18, 21, 13, 20;(the add 3.7 has no place in this data set .Ignore it)
1) arrange the data from smaller to greater: 13 13 15 17 18 20 21
2) mean: Add up all data & divide by the number of data
that is 7==> (117/)/7 so the mean = 16.71
3) Median is the central value of the data point that is in the middle of the sequence, so the median is 18
4) Mode the number that is most repeated & it's 13 (repeated twice)
5) The range is the difference between the largest & the smallest
Range = 21-13 ==> Range = 8
There is a problem in answers you have written: Either you mistyped or omitted something or the answer are false. With the data you gave me, my methodology is 100% right
Answer:
a. 3 in.
