Ho μ = 25, where μ = the mean number of students that prefer each type of food. Ho PR PT PP = PH = 0.25, where pR is the proportion of students in the school who would choose ramen, and so on. Ho p = 0.25, where p = the proportion of all students who prefer ramen. HonRnT = np = nH = 25, where ng is the number of students in the school who would choose ramen, and so on.
