Answer 1

Here is the answer

We know that,


$\bf{Mean = \frac{Sum \: of \: all \: observations}{total \: observations}}$


According to the question,

Let's find the mean of given enrollment.

$\bf{Mean=\frac{1555+1670 + 1750 + 2013 + 2540 + 2820}{6} }$


$\bf{ = \frac{12348}{6} }$


$\bf{= 2058}$


Hence,

The mean of the given enrollments is 2058.
