Solution:

Given, the data represents the cumulative frequency of the marks of the candidates.

We have to form the frequency distribution table from the data.

Marks out of 90

Number of candidates (cf)

Class interval

Frequency

More than or equal to 80

4

0 - 10

34 - 32 = 2

More than or equal to 70

6

10 - 20

32 - 30 = 2

More than or equal to 60

11

20 - 30

30 - 27 = 3

More than or equal to 50

17

30 - 40

27 - 23 = 4

More than or equal to 40

23

40 - 50

23 - 17 = 6

More than or equal to 30

27

50 - 60

17 - 11 = 6

More than or equal to 20

30

60 - 70

11 - 6 = 5

More than or equal to 10

32

70 - 80

6 - 4 = 2

More than or equal to 0

34
