A furniture factory produces 20 dining tables every day. The distributor that buys the tables randomly selects days to check the tables produced that day. Does this result in a simple random sampling?

Yes, the distributor's method of randomly selecting days to check the tables can be considered a form of simple random sampling. Each day has an equal chance of being chosen for inspection, which aligns with the principles of simple random sampling. However, the sampling is limited to specific days rather than individual tables, so it may not represent the overall quality of the tables produced every day.
