Given: 

The enrolment in a school during six consecutive years was as follows:

1555, 1670, 1750, 2013, 2540, 2820

To do:

We have to find the mean enrolment of the school for this period.

Solution:

Mean calculation

Mean enrolment $=\frac{ \text { Sum of all observations }}{ \text { Number of observations }}$

$=\frac{(1555 + 1670 + 1750 + 2013 + 2540 + 2820)}{6}$

$=\frac{(12348)}{(6)}$

$=2058$

Therefore, the mean enrolment of the school for this given period is 2058.
