Answer:
25%
Step-by-step explanation:
The median score of 70% indicates half of the student scored less than 70%.
An upper quartile of 85% means 3/4 of the students scored less than 85% or, stated in another way, 1/4 of the students scored above or equal to 85%.
From sentence 1, 50% of the students scored below 70%.
From sentence 1, 75% of the students scored below 85%.
The percentage that score between 70% and 85% is 75% - 50% = 25%
