$247$ and

$287$ .

$\frac{534 + 198 + 208 + 218 + 136 + 172 + 184 + 151}{9}$

Add

$534$ and

$198$ .

$\frac{732 + 208 + 218 + 136 + 172 + 184 + 151}{9}$

Add

$732$ and

$208$ .

$\frac{940 + 218 + 136 + 172 + 184 + 151}{9}$

Add

$940$ and

$218$ .

$\frac{1158 + 136 + 172 + 184 + 151}{9}$

Add

$1158$ and

$136$ .

$\frac{1294 + 172 + 184 + 151}{9}$

$1650$ and

$151$ .

$\frac{1801}{9}$

Step 3

Divide.

$200.\overline{1}$

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.

$200.1$
