the following data has been arranged in ascending order:
18,20,25,26,30,x,37,38,39,48
if the median of the data is 35, find x. in the above data if 48 is changed to 28 what will the new median be

Total number of observations = 10    (Even)

Median = 35102th observation+102+1th observation2=355th observation+6th observation2=3530+x2=3530+x=70x=70-30=40If 48 is replaced by 28, then the data arranged in increasing order is as follows:18, 20, 24, 25, 26, 30, 37, 38, 39, 40Median =26+302=562 =28
