Can I beat gym leader Whitney in Goldenrod City with this pokemon team?

I have a level 27 Cyndaquil who's male, a level 20 female Drowzee, a level 15 female Oddish, a level 12 male Togepei, a level female 10 Abra, and a level 14 female Hoot Hoot. Everytime I go up against Whitney, I lose. How can I finally beat her?
