En un estudio se determinó el tamaño de las particulas de distintos nanomateriales, los resultados se encuentran a continuación 46.4; 85.3; 31.1, 70.9; 2; 53.7; 99.2; 78.4; 11.2; 31.2; 56.3; 60.1; 76.8; 15.5; 5.2; 22.4; 65.2; 43.8; 93.5; 49.8

El valor de la varianza para estos datos es 865,1. La desviación estandar obtenida es 29,4; Este resultado nos indica que:

A.
Cada valor en promedio se aleja de la media en 29,4

B.
Cada valor en promedio se acerca a la media en 29,4

C.
El resultado de desviación estandar es erroneo por tal razon no se puede definir si cada valor se aleja o se acerca en promedio a la media 29,4
