th class, the professor shows a list of grades without names to summarize class performance on the quiz. The grades are: 55 30 99 54 79 60 63 91 52 63 33 87 71 90 84 89 93 95 58 78. a) Alice wants to learn her grade before the professor announces grades with names and she believes that she did better than 78% of the class. If her claim is true, what is the minimum grade she should expect? b) Professor gave Alice a clue by telling that she had scored around 85 points. Find the percentile rank using the method covered in the class AND the direct definition of the percentile. (Note: You have to provide 2 different solution approaches, not one).
