Question

the median of set of 9 distinct observation is 20 if each of the largest 4 observation of the set is increased by 2 find the median of the resulting set

Answer 1

Given, Median of Nine observations = 20 0

Median of 9 observations = 9+1/2 th term = 5th term.

Now, Fifth term = 20

The last term or the largest four are increased by 2 .But the fifth term is unchanged.

The median of resultant set is same as the earlier.

Hence median of resultant set = 20

Answer 2

Answer:

Step-by-step explanation:

given that,

Number of observation =9

Therefore median=(n+1÷2)

= 9+1÷2

=10÷2

= 5

Therefore 5th observation is 20

Largest 4 observation are increased by 2 it means 6,7,and 9 observation are increased by 2

Therefore the median of the resulting set is 20.
