Step 1

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

$\frac{37.3 + 35.3 + 34.7 + 27.9 + 15.1 + 12.1 + 12 + 9.5 + 8.6 + 8.4}{10}$

Step 2

Simplify the numerator.

Add

$37.3$ and

$35.3$ .

$\frac{72.6 + 34.7 + 27.9 + 15.1 + 12.1 + 12 + 9.5 + 8.6 + 8.4}{10}$

Add

$72.6$ and

$34.7$ .

$\frac{107.3 + 27.9 + 15.1 + 12.1 + 12 + 9.5 + 8.6 + 8.4}{10}$

Add

$107.3$ and

$27.9$ .

$\frac{135.2 + 15.1 + 12.1 + 12 + 9.5 + 8.6 + 8.4}{10}$

Add

$135.2$ and

$15.1$ .

$\frac{150.3 + 12.1 + 12 + 9.5 + 8.6 + 8.4}{10}$

Add

$150.3$ and

$12.1$ .

$\frac{162.4 + 12 + 9.5 + 8.6 + 8.4}{10}$

Add

$162.4$ and

$12$ .

$\frac{174.4 + 9.5 + 8.6 + 8.4}{10}$

Add

$174.4$ and

$9.5$ .

$\frac{183.9 + 8.6 + 8.4}{10}$

Add

$183.9$ and

$8.6$ .

$\frac{192.5 + 8.4}{10}$

Add

$192.5$ and

$8.4$ .

$\frac{200.9}{10}$

Step 3

Divide

$200.9$ by

$10$ .

$20.09$

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.

$20.1$
