So we're doing a randomized comparative design between clarinax and a placebo as to whether the patients will end up experiencing dry mouth.
00:11
And so the response variable is whether someone has dry mouth or not, that is qualitative, and the explanatory variable is the type of medicine taken, either the clarinx or the placebo.
00:24
The experiment is double blind, so the clinician, nor the patient knows which type of treatment.
00:30
Treatment he or she is getting.
00:32
And the placebo, it's important to have that placebo to see if the dry mouth happened just due to chance or was it the medication.
00:42
So we're having this as a control.
00:45
Now we would be assuming that the two proportions for dry mouth are equal.
00:49
This is the clarinax and this is the placebo.
00:52
And alternately, there's a higher rate here.
00:55
And this is a two proportion z test.
00:58
I have just entered that data in...
