Answer 2

Answer:  The median is 20.5

Step-by-step explanation:

First arranging all observations in ascending order

17,18,19,20,21,24,25,27...

now Median of even terms will be

M = { [n/2] + [(n/2) + 1 ] } /2   (( Brackets may be seen confusing ))

∴ M = { 4th term + 5th term } / 2

∴ M = {20 + 21} / 2

∴ M = 41/2

∴ M = 20.5
