The table below shows the percentage mark distribution of a number of candidates in a physics examination.
The table is in the attached image.
The completion of the table is :
Mark : 90-99
Frequency : 2
1. Make a cumulative frequency table and use it to draw the cumulative frequency curve.
II. from your graph estimate :
