Question

The following observation are arranged in ascending order. If the median of the data is 17. Find x if the observation are 6,8,9,15,x,x+2,21,22,25,29

Answer 1

Answer:

n=10(total observation)

median=17

therefore we use formula

median=(n/2th observation +(n/2+1)th observation)/2

Step-by-step explanation:

median =(10/2+(10/2+1))/2

17=(5th obser. + 6th obser.)/2

17x2= x+x+2

34=2x +2

32/2= x

x= 16
