During the medical check-up of 35 students of a class, their weights were recorded as follows: Draw a less than type ogive for the given data. Hence obtain the median weight from the graph and verify the result by using the formula.

Explanation

The graphical representation of cumulative frequency distribution is known as a cumulative frequency curve or an ogive.


The given cumulative frequency distributions of less than type are:


`(##X_RD_07_E01_40_s01##)`


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