00:01
All right, so we're playing with simulations.
00:02
And simulations are a fun way to see statistics in action, which is really, really quite cool.
00:10
So here's the sampling distribution applet, and we want to set it to binary distribution with a p equal to 0 .2, a success of 20%.
00:23
A proportion, because that's what we're doing with.
00:30
And then we do 100 ,000 random samples of substance.
00:34
This should say five.
00:37
When they wrote that down, i forgot to do that.
00:39
This should be five.
00:40
This is n equals five.
00:43
So we need to do that.
00:44
And then we're going to describe what we see.
00:46
So let's see.
00:46
We're going to do size five down here.
00:50
And if you run it one time, it's kind of neat.
00:52
It shows it to you.
00:55
The second time.
00:57
Oh, there we go.
00:57
Oh, look.
00:58
It's not perfectly in line, but it shows you the population proportion.
01:02
And then how many successes there are...
