Refer to 0.4 above. Draw the less then type ogive for this data and use it to find the median weight.

We observe that the number of packets less than 200 is 0. Similarly, less than 201 includes the number of pacakets from 0-200 as well as the number of packets from 200-201. So, the total number of packets less than 201 is 0+13=12. We say that , the cumulative frequency of the class 200-201 is 13. Similarly for other class.

To draw the less than type ogive we plot the points (200,0), (201,13),(202,40),(203,58),(204,68),(205,69) and (206,70) on the paper and join by free hand.
`therefore` Total number of packets(n)=70

Now, Firstly, we plot a point (0,35) on Y-axis and draw a line =35 parallel to X-axis. The line cuts the less than ogive curve at a point. We draw a line on that point which is perpendicular to x-axis. The foot of hte perpendicular to X-axis is the required meidan.
`therefore` Median weight=201.8g
