Question

the following observations have been arranged in ascending order if the median of the data is 63 find the value of x 29, 32, 48, 50, x, x + 2, 72, 78, 84, 95​

Answer 1

Answer:

x=62

Step-by-step explanation:

To find median  

first arrange it in ascending order (already done)

29 32 48 50 x x+2 72 78 84 95  

no. of elements is 10

so (10/2th+ 10/2 +1 the)/2

( 5th+6th )/2

x+x+2/2

2x+2/2=63

2x+2=126

2x=124

x=62

Answer 2

we know that while finding the median if the number of given observation is even then we have to add the middle two terms and divide it by 2

therefore,

median=sum of middle terms/2

63 = x+x+2/2

63 =2x+2/2

63*2=2x+2

126=2x+2

126-2=2x

124=2x

124/2=×

62=×
