INTRODUCCIN

Mediante la realizacin de esta actividad podemos establecer y aplicar los conocimientos adquiridos en las temticas de la unidad dos, donde por medio de la aplicacin de hiptesis podemos verificar acerca de una o ms poblaciones en un estudio estadstico, de igual manera con el anlisis de varianza podemos probar las hiptesis sobre la igualdad de tres o ms medias poblacionales o de la importancia de cules son las variables independencias en un estudio.PRUEBA DE HIPOTESIS.

Esta parte se la ha sacado de toda la poblacin.

Variable SEXO.Parmetro: proporcin de hombres Informacin.

Paso 1: hiptesis

No existan diferencias entre la proporcin de hombres y la de mujeres. La proporcin de hombres implicados en accidentes es mayor a la de mujeres.Paso 2: nivel de significancia (error tipo 1).Se establece un nivel un nivel de significancia de 0,1.Paso 3: Estadstica de prueba.

Paso 4: Estadstico terico

Paso 5: toma de decisin.Con un nivel de significancia de 10% la informacin proporcionada por la muestra no se rechaza la .

ANALISIS DE VARIANZA

Anlisis por medio Excel.

Para este anlisis de la varianza se ha tomado la variable cualitativa posible tipo de accidente con tres categoras: adelantar en curva o pendientes, exceso de velocidad y no mantener distancia de seguridad con relacin a la edad.

Comparando el valor crtico para la distribucin F con el valor F se evidencia que: Valor Critico FF, por lo tanto existe evidencia para aceptar la hiptesis nula.

Para este anlisis de la varianza tres se ha tomado la variable cualitativa Municipio con tres categoras: Albn, Cha, Villeta con relacin al caso de accidente.

Comparando el valor crtico para la distribucin F con el valor F se evidencia que: Valor Critico F>F, por lo tanto existe evidencia para aceptar la hiptesis nula.

CONCLUSIONES

En conclusin con la realizacin de esta actividad, como estudiantes de la UNAD podemos estar en la capacidad de identificar las tcnicas y procedimientos de la inferencia estadstica del mismo modo poderlas aplicar en estudios estadsticos poblacionales. De ah que podemos decir que estas tcnicas de inferencia se convierten en nosotros en herramientas para la toma de decisiones sobre hiptesis que se presente en nuestro futuro profesional.
