The correct option is D 34
Arranging data in ascending order- 17,26,29,32,33,34,45,56,60
Count of observations =9
Median for odd number of data is the middle most observation
So median =5th observation =33
If 26 is replaced by 62, then the observations in ascending order will be- 17,29,32,33,34,45,56,60,62.
Again Median for odd number of data is the middle most observation
So new median =5th observation =34
