How to solve simple random sampling
WebOne way to do it is associate every person in your school with a piece of paper and put 'em all in a bowl and then pick 'em out so let's do that. So let's say this is alphabetically the … WebIf you're randomly picking two campers, most of the time their consumption will balance out a bit, so σ for samples of 2 campers will be around 0.5L. σ for samples of 4 campers should be around 0.35L. For 50 random campers, Sal's probability estimate is right, if our initial assumptions are true.
