00:01 It's kind of an interesting question.

00:02 We would be assuming that the anxiety level, if we are going from easy to difficult, is equal to the anxiety level if the questions were difficult to easy.

00:14 And alternately, we just want to know if there's a difference.

00:17 And easy to difficult and not equal to difficult to easy.

00:24 And so we're going to assume that that difference is actually zero, so that the, i'll just write ed minus de, that that difference is zero.

00:36 And when i put this into my calculator, the lists have different sample sizes.

00:41 We have that first group of the e to d.

00:46 I have, there are 25 numbers versus the d to e.

00:51 There are 16 numbers.

00:53 And we could use a degrees of freedom of 15, but i'm going to use the degrees of freedom from the formula and that degrees of freedom ends up being 30 almost 39 so 38 point well i'm just going to call it 39 it's approximately 39 degrees of freedom and that test statistic that we're going to get we need to take the mean which was 27 .1152 minus the mean of the other group which was 31 .728 125 and then divided by the square root of and the first standard deviation i'll round that a bit is 6 .857 1 squared divided by the sample size which was 25 and then the second standard deviation was 4 .26 square divided by the sample size of 16 and when i got that test statistic the test statistic came out to be i'll just write it up here, negative 2 .656.

01:55 And so it came out down here.

02:00 And since we're doing a two -tail test, we'd also use this one...
