Final answer:
Without the full cumulative frequency table, it is not possible to accurately determine how many siblings the person with a cumulative frequency of 179 has. The cumulative frequency indicates how many individuals have 'at most' a certain number of siblings up to a point in the table.
Step-by-step explanation:
To answer how many siblings the person with a cumulative frequency of 179 has, we need more information about the frequency table that outlines the number of siblings corresponding to each cumulative frequency. Without the context of the frequency table, we cannot determine which category (a, b, c, or d) the cumulative frequency of 179 falls into.
In a typical cumulative frequency problem such as this, the cumulative frequency value indicates how many individuals (up until a certain point) have 'at most' a certain number of siblings. For example, if the person with a cumulative frequency of 179 is at the threshold for having 3 siblings, it means that 179 people have 3 or fewer siblings.
It's important to have the entire cumulative frequency table to be able to identify the exact number of siblings for a given cumulative frequency. Once we have the table, we can find the category where the cumulative frequency just exceeds or matches 179 to find out the total number of siblings.
