Question

2. Compute the mean of the following

Income 200-300 300-400 400-500 500-600 600-700 700-800 800-900

No of workers 5 36 24 16 9 6 4​

Answer 1

Answer:

answer

=700+20=720

Step-by-step explanation:

Hence 700-800are median

Thus,we have

l=700,c.f=68,f=35,h=100

thus,meduan=l+[n/2-c.f/f]×100

=700+[72-68/35]×100

=700×20=720
