Question

How many workers have weekly wages in the Class interval 525-700?​

Answer 1

Step-by-step explanation:

We have,

N=∑f

i

=100

⇒76+x+y=100⇒x+y=24

It is given that the median is 525. Clearly, it lies in the class 500−600

∴l=500,h=100,f=20,F=36+x and N=100

Now,

Median=i+

f

2

N

−F

×h

⇒525=500+

20

50−(36+x)

×100

⇒525−500=(14−x)
