Answer 1

The correct answer is:

The IQR is 2.75. This means that 2.75 hours is the range of the number of hours spent on the project for the middle 50% of the students.

This is because the IQR (Interquartile Range) represents the range of the middle 50% of the data. In this case, the IQR is 2.75 hours, indicating that for the middle 50% of students, the number of hours spent on the project ranged from 1.0 hours to 3.75 hours.
