This might seem like a random question but suppose someone was interested in estimating the total amount of laundry detergent consumed per a year within the united states. What sort of conceptual framework would you use to approach such a question? Obviously we will not have population level data in this case so statistics must be involved.
I would think the following would need to be incorporated
-Some form of random sampling (survey) at aggregated at the state level
-view the sampling distribution of the sample means
-get an average of per state, which will lead to annual consumption
What would you guys think?
