Answer 1

Answer:

first draw the table for median

classes. frequency cmf

2500-3500. 5. 5

3500-4500. x. 5+x

4500-5500. y. 5+x+y

5500-6500. 12. 17+x+y

6500-7500. 6. 23+x+y

7500-8500. 2. 25+x+y

median class =n/2=25/2=22.5 so median class=6500-7500

median=l+(n/2-cf/f)h

5000 =6500+(22.5-17+x+y/6)1000

5000=6500+(5.5+x+y/6)1000

5000-6500=(5.5+x+y/6)1000

-1500=(5.5+x+y/6)1000

-1500/1000=(5.5+x+y/6)

1.5=(5.5+x+y/6)

1.5*6=x+y

9=x+y

now you can easily find x,y values

hope this helps you
