Brief Explanations

Para la pregunta 1:
El hipótesis nula (\(H_0\)) se define como la afirmación de que no hay cambio o no hay efecto. Esto es una definición básica en estadística.
Para la pregunta 2:
El hipótesis alternativa (\(H_1\)) es la afirmación que el investigador está probando (una diferencia o efecto). También, es la negación de la hipótesis nula y aunque no se prueba directamente (se infiere a partir del análisis de la hipótesis nula), la mejor descripción es la de que es la afirmación que se busca probar (diferencia o efecto).

Answer:

  1. B. The claim that nothing has changed or there is no effect
  2. C. The claim the researcher is testing for (a difference or effect)
