So we have a sample of one, two, three, four, five, five people, and we have the systolic blood pressure measured on the right arm and the left arm.
00:11
And our difference is going to be to take the right measurement minus the left measurement.
00:16
And so we want to do a hypothesis at a 1 % significance level to find, and let's see, it says that we want to find, is there evidence at a 1 % significance level, that there's a different, between the two arms.
00:31
So this will be a two -tail test.
00:33
We're going to assume that the mean difference is equal to zero and alternately that the mean difference does not equal zero.
00:41
So we're not trying to show that one is higher than the other, just whether they are different.
00:47
Now, this will be a t test and a one sample t test.
00:52
And so i have my data again in list one, and we can utilize the software to do the whole thing and basically not show any values down.
01:03
And i do have to do one more quick thing.
01:07
I have to find those differences, which i have not done into my, this is in my list one, this is in my list two.
01:15
And my list three needs to be the difference between these two by list one minus list two...
