a. Ordene las observaciones en orden ascendente de acuerdo con los salarios, y divídalas en 5 partes
iguales, cada una conteniendo el 20% de las observaciones (quintiles). ¿Cuál es el rango de ingresos de
las personas que están en el quintil 1 (20% de la población con menores ingresos) y en el quintil 5 (20%
de mayores ingresos)?
Quintil 1 Quintil 2 Quintil 3 Quintil 4 Quintil 5
150 580 810 1.120 1.620
200 625 865 1.150 1.950
350 670 910 1.235 2.350
470 785 1.015 1.420 2.660
b. Con esos mismos datos, calcule la ratio de ingresos 80/20. Para ello, simplemente halle el cociente
entre el ingreso del trabajador que está en el percentil 80 y el que está en el percentil 20. ¿Qué significa
esa ratio?
