To solve the problem, we will create a frequency table based on the marks scored by the 20 students. We will categorize the marks into specified class intervals, tally the occurrences of marks in each interval, and then determine the frequency for each interval. ### Step-by-Step Solution: 1. **Identify the Marks**: The marks scored by the students are: 54, 42, 68, 56, 62, 71, 78, 51, 72, 53, 44, 58, 47, 64, 41, 57, 89, 53, 87, 57. ...
