Answer :

Given is the frequency distribution table for ungrouped data.

We have



25 number of parcels have weight each 50 kg,


34 number of parcels have weight each 65 kg,


And so on…


This also implies that,


Total weight of 25 parcels = 1250,


Total weight of 34 parcels = 2210,


And so on…


Mean of such ungrouped data is given by




[ ∑xifi = 17000 & ∑fi = 200]
