To construct a frequency table for the given marks of 30 students, we will follow these steps: ### Step 1: Identify the Range of Marks The minimum mark is 30 and the maximum mark is 82. We need to create class intervals starting from 30. ### Step 2: Define Class Intervals Given that one class interval is 30-40 (excluding 40), we will create the following class intervals with a width of 10: - 30 - 40 ...
