they’d vote for Feliz, and 19 were undecided.

Brown.

The sample statistic for the proportion is given by

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

To reduce, divide the numerator and denominator by their greatest common divisor, which is 5:

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

Thus, the sample statistic is $$\frac{23}{40}$$.

This suggests that we might expect $$\frac{23}{40}$$ of the voters to vote for Brown.
The sample statistic for the proportion of voters who said they'd vote for Brown is $$\frac{23}{40}$$. This suggests that we might expect $$\frac{23}{40}$$ of the voters to vote for Brown.
