Montana State University wants to survey its students about whether they think a 5% increase in next year€™s tuition is reasonable. Undergraduates who are given the Western Undergraduate Exchange (WUE) award pay lower tuition. Because WUE undergraduates, resident undergraduates, nonresident undergraduates, resident graduate students, and nonresident graduate students all pay different tuitions, the university plans to use these five types of students as strata. The strata sizes are shown in Table 19.

If the university wants to survey 900 students, how many students in each strata should be surveyed?
