The following tab

Answer :

We may compute class marks (xi) as per the relation


Xi=


Now, let assumed mean (A) = 30



∑fi=80, ∑fidi=430


Mean=


= 30 + = 30+ 5.375


=35.38


It represents that on an average the age of patients admitted was 35.38 years. As we can observe that the maximum class frequency 23 belonging to class interval 35-45.


So, modal class= 35-45


Lower limit (l) of modal class =35


Frequency (f1) of the modal class=23


h=10,


Frequency (f0)of class preceding the modal class=21


Frequency (f2) of class succeeding the modal class =14


Now,


=


=35 + 1.81 =36.8years
