Which hypothesis test would be used to answer this research question: Students at Hogwarts School of Witchcraft and Wizardry are asked to choose a career path. The different types of careers choices are Auror, Quidditch player, or Headmaster/Professor. Within the school, students are placed into one of four houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. Would we expect to see an equal proportion of students in each house to choose each career type?
