You're on a roll — 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
