**Step 1: Define the sample statistic**

The sample statistic for the proportion of voters who said they'd vote for Brown is given by the ratio

$$
\frac{\text{Number of voters who chose Brown}}{\text{Total number of voters surveyed}}
$$

**Step 2: Substitute the given values**

Given that 115 voters said they'd vote for Brown and the total number of voters surveyed is 200, we have

$$
\frac{115}{200}
$$

**Step 3: Reduce the fraction**

Divide both the numerator and the denominator by their greatest common divisor, which is 5:

$$
\frac{115 \div 5}{200 \div 5} = \frac{23}{40}
$$

**Step 4: State the final answer**

The sample statistic for the proportion of voters surveyed who said they'd vote for Brown is

$$
\frac{23}{40}.
$$
The sample statistic for the proportion of voters surveyed who said they'd vote for Brown is $$\frac{23}{40}$$.
