Construct a grouped frequency distribution table with a class width of $10$,such that one of the classes is $10-20$ ($20$ not included).
(N/A) To construct the grouped frequency distribution table,we count the number of students falling into each class interval of width $10$. The data is distributed as follows:
| Class Intervals | Frequency |
| $0-10$ | $4$ |
| $10-20$ | $7$ |
| $20-30$ | $5$ |
| $30-40$ | $6$ |
| $40-50$ | $5$ |
| $50-60$ | $8$ |
| $60-70$ | $5$ |
| $70-80$ | $8$ |
| $80-90$ | $5$ |
| $90-100$ | $7$ |
