<reasoning>

Ordenar el conjunto de datos

\[
12, 23, 26, 27, 28, 30, 31, 34, 34
\]

Comparar con el límite inferior

\[

$$\begin{aligned} &\text{Límite inferior} = 12.5 \\ &12 < 12.5 \end{aligned}$$

\]

Determinar la existencia de valores inferiores

\[
\text{Existe el valor } 12 \implies \text{Sí}
\]
