Con la esperanza de atraer más viajeros, una compañía de transportes urbanos planea tener servicio de
autobuses express de una terminal suburbana al centro fi nanciero de la ciudad. Estos autobuses deben
ahorrar tiempo de viaje. La ciudad decide realizar un estudio del efecto de cuatro planes diferentes (por
ejemplo un carril especial y semáforos sincronizados) en el tiempo de viaje de los autobuses. Los tiempos
de viaje (en minutos) se miden para varios días hábiles durante un viaje en horas pico cuando cada
uno de los planes se está aplicando. Los resultados aparecen en la tabla siguiente.
