Hi, I don’t get well.
If we want to conduct a survey at exact town why should we care about population of the whole world (100.000). If for population size we can take 1700. Maybe the preferences of this city is specific. Thank you in advance!

Same here. Can someone help us?

Same doubt here too , please answer

I’ve never seen a member of Codecademy’s team respond to these threads.

In any event, I came here to refute that margin_of_error is meant to be 4. 4% would be 0.04.

I think to decide upon the population size as a shop owner, you wouldn’t consider only the people from your town as customers. For example, a customer can come in from out of town. So you want a large population size.
