$\overline{x}=4$

#### Work Step by Step

The mean $\overline{x}$ of a set of data with $n$ values can be found using the formula: $\overline{x} = \dfrac{\sum{x}}{n}$ (sum of all the items divided by the number of values). Solve for the mean using the formula above to obtain: $\overline{x}=\dfrac{11+6+4+0+2+1+12+0+0}{9} = \dfrac{36}{9} = 4$
