Question

Philoid · Accepted Answer

Here,

We have to find the mean of the given enrolments of the school

Now,

At first,

We’ll find the sum of all the observations

Thus,

Sum of all the observations = 1555 + 1670 + 1750 + 2013 + 2540 + 2820

= 12348

Now,

Total number of observations = 6

Hence,

Mean enrolments =

=

= 2058
