HELP PLS!! JoAnna is in a mathematics class of 25 students that participated in this test. JoAnna knows that she scored an 80 on the test and reasons that, since only 2.5% of the students score above a 75 and there are only 25 students in her class, that it is highly likely that she received the top score of all the students in her class. Is this good reasoning?
