Okay, so you're finding the probability that your z score, that's what the z score, is between 0 .01 and 2 .59.
00:13
So this is your normal distribution, and this, let me make this just a touch thicker, is what your distribution would look like.
00:27
So the z score is zero.
00:30
Right in the middle is your mean, right? and these are positive numbers, 0 .01, up to 2 .59, which is going to be like clear to here.
00:47
So we're finding this area right here.
00:56
That's the area we're looking for.
00:58
So we're going to find that by using this table here.
01:02
Now, these numbers are all positive.
01:04
So i'm going to go down to the next page.
01:07
So we're going to start by looking for 0 .01.
01:11
So if you notice on here, on this side, the far left column, and across the top, that's for your z score.
01:21
Everything in the middle are your probabilities.
01:25
Okay? so 0 .01.
01:28
0 .0 is right here.
01:32
0 .0.
01:34
And then we want 0 .01.
01:41
And so this is where it overlaps.
01:46
0 .5040.
01:50
So 0 .5040.
01:58
Okay.
01:59
We'll talk about what that means in a second.
02:02
So 2 .59...
