70-75

75-80

No. of runs

2

8

12

24

38

Answer:

We can obtain cumulative frequency distribution of more than type as following - 

Over

(lower class limits)

Cumulative frequency

More than or equal to 50

100

More than or equal to 55

100 - 2 = 98

More than or equal to 60

98 - 8 = 90

More than or equal to 65

90 - 12 = 78

More than or equal to 70

78 - 24 = 54

More than or equal to 75

54 - 38 = 16

Now taking lower class limits on x-axis and their respective cumulative frequencies on y-axis we can obtain its ogive as follows.
