Over time, Erin has become suspicious that the "random" play function on her music player is not truly random. Specifically, she thinks that her music player might have a preference for 80s power ballads. Being a woman of science, she decides to test her hypothesis. She sets her music player to "random", listens to 12 songs, and records whether or not an 80s power ballad was played each time. Out of the 12 songs, 5 of them are 80s power ballads. Given that Erin's music collection consists of 25% 80s power ballads, 30% obscure German electronica, 40% whale songs, and 5% self-recordings of monologues about whale songs, is Erin's result sufficient to support her suspicions concerning the musical tastes of her player?
