Solution

Para responder a la pregunta, primero debemos analizar el gráfico de puntos proporcionado. Sin embargo, como no se ha incluido el gráfico en la pregunta, describiré cómo proceder si tuviéramos acceso a él.

  1. Identificar la simetría:

    • Un gráfico es simétrico si ambos lados del gráfico son aproximadamente una imagen especular uno del otro.
    • Si los puntos están distribuidos de manera uniforme a ambos lados de un punto central, el gráfico es simétrico.
  2. Identificar el pico:

    • El pico del gráfico es el valor con la mayor frecuencia, es decir, el valor que tiene más puntos sobre él.

Dado que no tenemos el gráfico, no podemos determinar con certeza la simetría ni el pico. Sin embargo, si asumimos que el gráfico tiene un pico en 3 o 4 y es o no simétrico, podemos considerar las opciones:

  • Si el gráfico es simétrico y tiene un pico en 3, la opción correcta sería: "It is symmetric and has a peak at 3."
  • Si el gráfico es simétrico y tiene un pico en 4, la opción correcta sería: "It is symmetric and has a peak at 4."
  • Si el gráfico no es simétrico y tiene un pico en 3, la opción correcta sería: "It is not symmetric and has a peak at 3."
  • Si el gráfico no es simétrico y tiene un pico en 4, la opción correcta sería: "It is not symmetric and has a peak at 4."

Para proporcionar una respuesta precisa, necesitaríamos ver el gráfico de puntos.
