Final answer:
The frequency of students in the interval 40-45 is 10, which is directly given in the list of provided frequencies for each interval.
Explanation:
The frequency of students in the interval 40-45 can be determined from the given frequencies corresponding to specific intervals.
Based on the information provided, the intervals and their corresponding frequencies are as follows:
- 5-10: 10 students
- 10-15: 25 students
- 15-20: 18 students
- 20-25: 5 students
- 25-30: 20 students
- 30-35: 35 students
- 35-40: 40 students
- 40-45: f students
Since the median marks are 24, the distribution's midpoint (50th and 51st data points) fall in the interval 20-25, which means that all intervals after 20-25 would have students scoring more than 24.
Thus, the frequency for the interval 40-45 would be the last frequency given, which is 10.
