Question

Find the value of y from the following observations if these are already arranged in ascending order. The Median is 63.

20, 24, 42, y , y +2, 73, 75, 80, 99​

Answer 1

answer is 62

Step-by-step explanation:

median=(N+1)/2

= (8+1)/2

=4.5

So we have,

median=4.5th item

or,63= (4th item+5th item)/2

or, 63= (y+y+2)/2

or,63×2= 2y+2

or,126=2y+2

or,126-2=2y

or,124=2y

or,124/2=y

or,y=62
