Change the distribution to a more than type distribution, and draw its ogive

The frequency distribution table of more than type graph is as follows:


Production yield


(lower class limits)



Cumulative frequency



More than or equal to 50



100



More than or equal to 55



98



More than or equal to 60



90



More than or equal to 65



78



More than or equal to 70



54



More than or equal to 75

Now,


Taking lower limit on x-axis,


Cumulative Frequencies on y- axis,


Its ogice can be drawn as:
