To present the given marks of 40 students in the form of a frequency distribution table, we will follow these steps: ### Step 1: Determine Class Intervals We need to create class intervals based on the given data. The question specifies one class as 10-15 (15 not included). We will create additional classes around this interval. - Class intervals can be: - 0 to 5 (5 not included) - 5 to 10 (10 not included) ...
