Here's the solution to the problem:
a. Construct a cumulative frequency table for the distribution
Step 1: Determine the upper class boundaries and calculate the cumulative frequencies.
The upper class boundary for a class like 1-10 is 10.5, for 11-20 is 20.5, and so on. The cumulative frequency (CF) is the running total of the frequencies.
| Class | Frequency (f) | Upper Class Boundary | Cumulative Frequency (CF) |
|---|---|---|---|
| 1-10 | 3 | 10.5 | 3 |
| 11-20 |
