1. Hacer una Estadística descriptiva de la variable IMC.
2. Comprobar el ajuste de la variable IMC a la distribución normal mediante la Asimetría estandarizada y la Curtosis estandarizada y resumirla apropiadamente.
3. Calcular y valorar las correlaciones entre las tres variables cuantitativas: Edad, IMC y TVdiaria. Calcular esas mismas correlaciones entre las tres variables cuantitativas en hombres y en mujeres por separado.
4. Hacer una Estadística descriptiva de las variables Antidepresivos y Trabaja.
5. Construir un intervalo de confianza del 95% de la media de la IMC en hombres y uno en mujeres.
