.
Pls answer as soon as possible.
10 points and will be marked as brainliest

Answer:
now take cf at y axis and less than type frequency on x axis
after this divide half of the frequency from y axis to the less than ogive
from that point draw a perpendicular to x axis
at the point of the perpendicular on x axis that will be the frequency of the given data
if you are army then follow me I'll follow back you
hope this answer help you
Median = 40.6
Step-by-step explanation:
Class f cf
10 - 20 40 40 Less than 20
20 -30 22 62 Less than 30
30 - 40 35 97 Less than 40
40 - 50 50 147 Less than 50
50 - 60 23 170 Less than 60
60 - 70 30 200 Less than 70
Median = 40 + 10 ( 100 - 97)/50
= 40 + 3/5
= 40 + 0.6
= 40.6
Median = 40.6
Less than ogive
The points with the upper limits of the class are plotted on x axis and the corresponding less than cumulative frequencies on y axis.
The points are joined by free hand smooth curve to give less than cumulative frequency curve or the less than Ogive
