Identify which of the following situations involve sampling from a finite population and which involve sampling from infinite populations: (8 Points)
1. Obtain a sample of personal banking customers for a major Canadian bank
This would be considered finite population because the number of personal banking customers is not infinite. There are other major Canadian banks, not just one.
2. Obtain a sample of smartphones produced at an assembly line
3. Obtain a sample of inbound customer service calls for the call centre of a large telecommunication company
4. Obtain a sample of accounts receivable records for a mid-size trading company
I have answered 1. But am still confused on this concept. I think I am always viewing these problems in a "real world" or "humanly possible " scenario as opposed to a textbook theory. I honestly feel like these all could be Finite but am not sure.
Anyways, any help with explanantion would be greatly appreciated. Happy New Year!
