C. The IQR is 2.5. This means that 2.5 hours is the range of the number of hours spent on the project for the middle 50% of the students.
The IQR (Interquartile Range) is a measure of statistical dispersion, or in simpler terms, it represents the range of the middle 50% of the data. In this case, since the IQR is 2.5 hours, it means that the middle 50% of students spent between 1.0 to 3.5 hours on their project.
