Actually bean counting: Find standard deviation given population ratio, size of sample and number of samples.

15 Views Asked by At

I've been Googling and raking my brain over college statistics for the past hour, but can't seem to find a solution for this particular situation:

So, I have a lot of beans (assume an infinite sized population of beans) evenly mixed at a ratio of 1 red bean : 100 green beans.

Say I take 30 random samples of 4200 beans each. What would be the standard deviation of the number of red beans these samples?

Ultimately, I need to create some sort of visual probability distribution curve that shows the expected distribution of red beans across 30 random samples. What formulas should I use for this particular situation?

Any guidance at all would be deeply appreciated!
