Expert Solution
Step 1

A)

The third quartile, represented as Q3, is the number such that 75% of the observations are less than it and the remaining 25% of the observations are larger than it.

 

Here, the third quartile Q3=3.39 can be interpreted as about 75% of the students have a GPA below 3.39 and the remaining 25% of the students have s GPA above 3.39.

 

Hence, 25% of the students in the sample had a GPA above 3.39.
