00:01
All right, so we've got some hospitals, 29 of them to be exact, in cincinnati, ohio, and kentucky.
00:10
And they're each given a number, 0 to 28.
00:13
They're classified by type.
00:16
And we want to estimate the average number of full and 10 nurses and put in the area.
00:19
So we're going to sample five hospitals.
00:23
And some random numbers are generated, so which hospitals are included based on those numbers.
00:29
So 9, 16, 0, 49, and so on and so forth.
00:32
Do that.
00:32
So nine, you just read the number here.
00:36
So nine, we got the children's hospital here.
00:39
That's one of them.
00:42
You just read off the number.
00:44
So nine is children's hospital.
00:46
Sixteen is st.
00:49
Francis, that one.
00:52
Forty -0, zero, that's this guy up here, bethesda, that one.
00:57
49 and 54 are not included because our numbers only go to 28.
01:02
And so we have the 12th one and the fourth one.
01:04
The fourth one is mercy hospital in hamilton, ohio.
01:10
And then number 12, we've got good samaritan.
01:13
There we go.
01:14
So those are the hospitals selected.
01:17
Using a random number generator, develop your own sample of five hospitals.
01:23
So there's no hard and fast rule for using your random number table, which i have right here.
01:29
Here's one i found.
01:30
You just pick some criteria and you stick to it.
01:34
So it's, let's see, it's 840 right now, my time, 840.
01:46
So i'm going to say we pick the every eighth row and then we pick four.
01:57
Let's see how we do this.
02:01
Starting with the eighth row, we count every four cells and we take the number.
02:06
So one, two, three, four, five, six, seven, eight.
02:09
Okay, so we'll start here and we pick every fourth.
02:12
So we've got one, two, three, four.
02:14
Okay, so we're going to pick that one.
02:16
And then we go one, two, three, four, one, two, three, four.
02:21
One, two, three, four.
02:21
And you just kind of keep rolling down.
02:24
One, two, three, four.
02:29
One, two, three, four.
02:31
One, two, three, four.
02:33
One, two, three, four.
02:36
One, two, three, four.
02:40
I mean, hoping you're seeing there's nothing crazy i'm doing here.
02:43
One, two, three, four.
02:44
You just make a pattern.
02:47
If it's a random number table, it should be, pretty okay.
02:50
All right, so let's go ahead and see what we have.
02:51
So we've got the 28th.
02:55
We've got one already.
02:56
So 28 will work.
02:59
And then we read the first two numbers.
03:00
We got 11.
03:02
And then we go 57.
03:04
That's not going to work, but we're going to keep track of it.
03:06
And then 23.
03:08
And then we've got 8.
03:11
08 is that.
03:12
So i'm going to say 8.
03:13
That's how we get singles here.
03:14
Singletes.
03:16
Then we've got 32.
03:18
And then we've got 19.
03:22
One two three yeah this will work we have enough so we go through here and pick the five so it'd be the 28th based on this eight 40 time so we have that one the va hospital based on that criteria the 11th one which is the deaconess we got the 57th no we don't have one 23 we've got 23 in the 8th and the 19th so the 19th one is st...
