FUNDAMENTALS OF MATHEMATICAL STATISTICS A number of particular articles has been classified according to their weights. After drying for two weeks the same articles have again been weighted and similarly classified. It is known that the median weight in the first weighing was 20.83 gm. while in the second weighing it was 17.35 gm.

A number of particular articles has been classified according to their
weights. After drying for two weeks the same articles have again been weighted and similarly
classified. It is known that the median weight in the first weighing was 20.83 gm. while in the
second weighing it was 17.35 gm. Some frequencies a and b in the first weighing and x and y
in the second are missing. It is known that a = x and b = y. Find out the values of the
missing frequencies.
