Question

find the value of median 2.3,x.x+2.11.17 is 9 ( the observations are arranged in assending order of magnitude) please answer correctly

Answer 1

Answer:

Value of x is 8 when median is 9

Step-by-step explanation:

median = middle most value

for n(number of terms)=even

2 mean= value of (n/2)th tem +value of (n+1)/2 th term

=value of 3rd term + value of 4th term

2(9)=x+x+2

18=2x+2

16+2x

therefore, x=8

Answer 2

Answer:

the observations are : 2.3 , x , x+2 , 11 , 17

median is simply  the middle term of the observations when they are arranged acending or decending order

in the given observations .,

the middle term is x+2

median = 9 (given)

x+2 = 9

x= 9 - 2

x= 7
