Final answer:
Without specific data, smaller intervals such as 2 or 4 are generally more suitable for a classroom-sized survey to create a frequency table, as they provide detail while keeping the table readable.
Step-by-step explanation:
To graph information into a frequency table from a survey that asks how many books students read over the summer, one must consider the range of data and the number of intervals that will best represent that data. Choosing an interval is a balance between having enough detail and not having so many intervals that the table becomes difficult to interpret.
Without the specific data, it is challenging to choose the most appropriate interval. However, typically, smaller intervals like 2 or 4 provide a more detailed distribution than broader intervals like 10 or 20, assuming the range of the number of books read is not excessively large. For a classroom-sized survey, intervals of 2 or 4 are often sufficient to provide a clear picture of the data while maintaining readability.
