Responder:

Media

Explicación paso a paso:

Primero debemos saber que cambiar el valor de 6 a 7 no puede cambiar la mediana y la moda de los datos, ya que la moda es el valor que más ocurre, que es 3, mientras que la mediana es el valor tq en el medio después del reordenamiento.

La única medida de tendencia que cambiará es la media (datos promedio)

Vamos a revisar

Encuentra la media de dos datos originales

Media = 3, + 4, + 6 + 3, + 5 + 5 + 6 + 3 + 4/9

Tamaño de muestra = 9

Media = 39/9

Media = 4,33

Si uno de los 6 se reemplaza por 7, la media se convierte en

Media = 3, + 4, + 6 + 3, + 5 + 5 + 7 + 3 + 4/9

Tamaño de muestra = 9

Media = 40/9

Media = 4,44

Podemos ver que cambió el valor medio. Por tanto, la respuesta correcta es la media.
