The median of the following observation arranged in ascending order is 24 . Find x. 14, 18 , x+2, x+4 , 30, 34 . Using the the value of x . find the mean of the above data.
No of observations=7
Median= n+1/2
=(7+1)/2
=8/2
=4th Observation
=x+2=24
x=24-2
x=22
Mean= Sum of observations/No of Observations.
= (22+14+18+24+26+30+34)/7
=168/7
=24
