Now depending on how you're being taught, this is technically a t test.
00:19
Some textbooks will say if the sample size is sufficiently large just to go ahead and use a z value.
00:26
And you may be taught that way.
00:27
But i have my students do a t.
00:30
And so you can do this as a two sample t test.
00:36
And you will get that the test statistic is 1 .13.
00:42
And so all of those have that test statistic.
00:45
And it says is there sufficient evidence at a 5 %? and the answer is no.
00:51
It is not sufficient because the pvis two -tail test, when we find the p value for this, we would end up getting that the p value i have for a t test is actually .259.
01:11
And it would round to 7...
