Question

The following observations have been arranged in the ascending order. if the median is 45. find x
The observations are : 29,32,48,50,x,x+2,72,78,84,95

Answer 1

Answer:

x=44

Step-by-step explanation:

given that,

median= 45

n= 10 (even)

(n÷2)th observation + (n÷2+1)th observation ÷ 2

(10÷2)th observation + (10÷2+1)th observation ÷2

5th observation + 6th observation ÷ 2 = 45

x+x+2÷2=45

2x+2÷2=45

2(x+1)÷2=45

x+1=45

x=45-1

x=44
