Step 1

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

$\frac{88 + 110 + 123 + 163 + 181 + 185 + 107 + 247 + 135 + 139 + 115 + 250}{12}$

Step 2

Simplify the numerator.

Add

$88$ and

$110$ .

$\frac{198 + 123 + 163 + 181 + 185 + 107 + 247 + 135 + 139 + 115 + 250}{12}$

Add

$198$ and

$123$ .

$\frac{321 + 163 + 181 + 185 + 107 + 247 + 135 + 139 + 115 + 250}{12}$

Add

$321$ and

$163$ .

$\frac{484 + 181 + 185 + 107 + 247 + 135 + 139 + 115 + 250}{12}$

Add

$484$ and

$181$ .

$\frac{665 + 185 + 107 + 247 + 135 + 139 + 115 + 250}{12}$

Add

$665$ and

$185$ .

$\frac{850 + 107 + 247 + 135 + 139 + 115 + 250}{12}$

Add

$850$ and

$107$ .

$\frac{957 + 247 + 135 + 139 + 115 + 250}{12}$

Add

$957$ and

$247$ .

$\frac{1204 + 135 + 139 + 115 + 250}{12}$

Add

$1204$ and

$135$ .

$\frac{1339 + 139 + 115 + 250}{12}$

Add

$1339$ and

$139$ .

$\frac{1478 + 115 + 250}{12}$

Add

$1478$ and

$115$ .

$\frac{1593 + 250}{12}$

Add

$1593$ and

$250$ .

$\frac{1843}{12}$

Step 3

Divide.

$153.58\overline{3}$

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.

$153.6$
