So i've entered the data for your sample of eight, and these are from a fixed rate.
00:06
And i have entered those into my list one.
00:09
And i've taken the variable rate, we'll just call that m sub v, into, and that's a sample of five, into my list two.
00:19
And you would be assuming, you want to find out if you have a difference between the two rates, so you're going to assume that the list from the, i'll call this one the first one and this one the second one, that the means are equal, and alternately, that there is a significant difference.
00:36
And it doesn't really indicate that you're thinking, or they're thinking that, they just want to find out if there's a difference.
00:42
So it just says if they differ, not that they're going to end up having one direction.
00:47
It says, choose an appropriate level of significance.
00:51
Well, typically, if we aren't told anything, i use a 0 .05.
00:56
And so it tells you that the test statistic p -value, and i give you those.
01:02
And i have those, this is a two sample t -test, because there are two independent samples.
01:12
So i'm just going to go stat and test on my calculator, the two sample t -test.
01:18
I have the data stored in my list one and list two.
01:21
And i'm not going to pool the standard deviations.
01:24
I'm not going to assume that they're equal.
01:25
And i actually don't have that p, that test statistic, excuse me, being what you have.
01:32
Sorry about that.
01:33
I actually even changed what i had on my calculator.
01:35
It slipped out...
