Last year, I gave a final exam to 200 students. Suppose the fivenumber summary of the grades was 40, 58, 65, 79, 90. Assume that no two people received the same score. Use this five-number summary to answer the following questions:
(b) In our survey, 75% of the class scored above what grade?
(c) How many students scored above 65? (Your answer should be the number of students, not a percentage.)
(d) In our survey, 150 students scored below what grade?
