Step-by-step explanation
to plot this, you need to count the numbers of weigth for that number, for example
for 18
count in the table all the 18
you will get 18 is 2 times in the table (2)
now, for 19
count the number of 19's in the table 3
and so on
Step 1
then, for 24
total = 0
so, as we have not 24 as a data, there is not need to plot it
I hope this helps you
