a) To find Evie's percentile rank, we first need to calculate how many students scored lower than her. There were 58 students in total, and 3 got the same mark as Evie and 2 scored higher. Therefore, 58 - 3 - 2 = 53 students scored lower than Evie.
Evie's percentile rank = (53/58) x 100 = 91.4%. So, Evie's percentile rank is 91.4%.
b) Evie's percentage on the quiz can be calculated by dividing her mark by the total possible marks and then multiplying by 100.
Evie's percentage = (52.5/90) x 100 = 58.3%. So, Evie scored 58.3% on the quiz.
c) Evie's percentile rank tells us that she performed better than 91.4% of the students who wrote the quiz. Her percentage on the quiz tells us that she scored 58.3% of the total possible marks. This indicates that the quiz was challenging, as most students scored lower than 58.3% and only a small number scored above that.
