A researcher interviewed randomly selected US Congress members and asked about their views on the use of nuclear energy. The table above summarizes the responses of the interviewees.

$$\text{Views on Nuclear Energy Use}$$ $$\begin{array} {|l|c|} \hline \hphantom{1em} \text{Response} & \text{Frequency} \\ \hline \text{Strongly favor} & 5 \\ \hline \text{Somewhat favor} & 11 \\ \hline \text{Neutral} & 18 \\ \hline \text{Somewhat oppose} & 14 \\ \hline \text{Strongly oppose} & 2 \\ \hline \end{array}$$

According to the table, $p$ percent of the interviewees responded "neutral" when asked about their views on the use of nuclear energy. What is the value of $p$?

We are asked to find the percent of all interviewees that responded "neutral".

$$\text{Views on Nuclear Energy Use}$$ $$\begin{array} {|l|c|} \hline \text{Response} & \text{Frequency} \\ \hline \text{Strongly favor} & 5 \\ \hline \text{Somewhat favor} & 11 \\ \hline \text{Neutral} & \colorbox{aqua}{$18$} \\ \hline \text{Somewhat oppose} & 14 \\ \hline \text{Strongly oppose} & 2 \\ \hline \end{array}$$ $$\frac{\text{responded neutral}}{\text{all interviewees}}$$ $$=\frac{18}{5+11+18+14+2}$$ $$= \frac{18}{50}$$ $$= \frac{36}{100}$$ $$= \boxed{36} \text{ percent}$$
