Draw a ‘less than type ogive’ and a ‘more than type ogive’ for this distribution.

Answer 1

The frequency distribution table of less than type is as follows:

Taking the lower class limits on x-axis and their respective cumulative frequencies on y-axis, its ogive can be obtained as follows

Now, 

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

Taking the lower class limits on x-axis and their respective cumulative frequencies on y-axis, its ogive can be obtained as follows:
