Answer 1

The median of set of 9 distinct observations is 20.5. If each of the largest 4 observations of the set is increased by 2, then the median of the new set remains the same as that of the original set.

No. of observations = 9

∴ median = 5th observation

∵ The largest four observations are increased

∴ 5th observation remains unchanged.
