Question

If the median of 7 , 4 , 2 , 3 (AED) 신기 b is 4.5 Then find & ?​

Answer 1

Answer:

The given data is 

5,7,7,8,x,5,4,3,1,2

Now, 

Mean=number of observationssum of observations 

∴4.5=105+7+7+8+x+5+4+3+1+2

⇒45=x+42

⇒x=45−42=3

Now, rearranging the observations, we get

1,2,3,3,4,5,5,7,7,8

total number of observations =10, which is even

Therefore, median= 24+5=29=4.5
