Answer 2

Answer:

mode is {15-20) as it has high frequency.

class x frequency F. CF

5-10. 5. 5

10-15. 7. 12

15-20. 11. 23

20-25. 8. 31

25-30. 10. 41

30-35. 3. 44

35-40. 2. 46

N=46

median =(N/2)th term =46/2=23 th term

in CF column just equal to 23 is 23

median class =(15-20)

median =15+ (23-12)/11×5=20
