Expert Solution
Step 1
Note : We’ll answer the first question since the exact one wasn’t specified. Please submit a new question specifying the one you’d like answered.
a) It is given that first class should be 40-44 and after this class, remaining classes should have equal width.
Therefore remaining classes should be like 44-48,48-52,52-56,...,76-80
Frequency distribution table:
| Class | Frequency |
| 40-44 | 2 |
| 44-48 | 4 |
| 48-52 | 8 |
| 52-56 | 11 |
| 56-60 | 8 |
| 60-64 | 5 |
| 64-68 | 3 |
| 68-72 | 4 |
| 72-76 | 0 |
| 76-80 | 1 |
