Draw both ogives for the above data. Hence obtain the median production yi
20
Step-by-step explanation:
We can obtain cumulative frequency distribution of more than type as following:
Production yield
(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 the ogive as follows.
