Answer 1

The final exams have the smaller IQR

Answer 2

To find interquartile range, you have to find quartile 1 and quartile 3. Then, you subtract to two to find interquartile range. To solve this problem, I first found quartile 1 and quartile 3 which are 80 and 92, respectively. Then I subtracted 80 from 92 which got me the interquartile range for the midterm data. Then, to find the interquartile range for the finals data, I did the same thing and I got 78 and 85 which gave me an interquartile range of 7. So, for the answer, I got c. the final exams.
