Question 1193248: Erika’s teacher summarized the achievement test results of her class in the table below. If Erika belongs to this class and her score is 76, does she belong to the upper 25% of her class? Justify your answer.
Score _ f
90-99 _ 3
80-89 _ 4
70-79 _ 6
60-69 _ 11
50-59 _ 8
40-49 _ 5
30-39 _ 3 Answer by greenestamps(13200) (Show Source):
The total number of scores is 40; the top 25% would be the top 10 scores.
We can tell from the given data that the cutoff for the top 25% is somewhere between 70 and 79; but we can't tell whether or not the score of 76 is in the top 25%.
