Step 1

The mean of a set of numbers is the sum divided by the number of terms.

$\frac{16.74 + 15.53 + 16.74 + 10.62 + 10.62 + 7.55 + 7.25 + 11.28}{8}$

Step 3

Divide

$96.33$ by

$8$ .

$12.04125$

Step 4

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.
