Question

the mode in the above frequency distribution table is (a)10 (b) 15 (c) 25 (d) 30​

Answer 1

Answer:

here is your answer!!

The cumulative frequency Table is:-

Class Frequency Cumulative frequency

0-5 10 10

5-10 15 25

10-15 12 37

15-20 20 57

20-25 9 66

Here,

2

N

=

2

66

=33

Thus 37 is just greater than 33,

∴ The median class is "10−15."

The lower limit of the median class is 10.

Modal class = class with maximum frequency.

∴ Modal class is 15−20.

The lower limit of the modal class is 15.

Sum of lower limits of median class and modal class = 10+15=25

Answer 2

Step-by-step explanation:

Class frequency. Cf

0 - 5. 10. 10

5 - 10 15. 25

10 - 15. 12. 37

15 - 20. 20. 57

20 - 25. 9. 66

Modal Class = Class with maximum frequency

• ° • Modal Class = 15 - 20

Sum of lower limit of median class and modal class

Modal class = 10 + 15 = 25
