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

Answer 1

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

Answer 2

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
