Take the following as truth: However, when we analyze the per-household volume figures, we have to remember that, for the purpose of developing those figures, we made the aforementioned assumption about the relationship of mail volume and number of households and this assumption may not hold true for some or all sectors (or uses) and for some or all years in Tables 1, 2 and 3.
Then the following statement: "The assumption is a waste of space and time" is true, false, or inconclusive?
Answer: Inconclusive
