So for your problem, you didn't list your data down.
00:04
You just put your questions down.
00:05
You are doing a chi -square test.
00:07
So i'm going to assume that there was a drug information, and then maybe that there is a placebo.
00:15
And then this is whether they had an adverse effect.
00:19
And this is yes, and this is no.
00:22
And so your first a says that the drug treatment and adverse effects are independent.
00:37
Adverse effects are independent versus for the alternative that they are not independent.
00:51
And you call that h sub 1.
00:53
Some techs call it h sub 0.
00:55
Drug and adverse effects are not independent.
01:03
So that is the correct value for this value.
01:07
Now, what i'm going to suggest you do is you enter this data into a matrix.
01:16
And the matrix will be, in this case, hopefully a 2 by 2 matrix.
01:22
And then you perform a stat test and a chi -squared test and get the chi -squared statistic.
01:34
And you want that value listed to three decimal places...
