I have a clinical trail where all the patients are suffering from a stroke.
Half of the patients got drug and the other half got placebo.
I need to assess the efficacy of the drug treatment for the entire sample by using the chi-square test in excel.
I have the values if the treatment(drug/placebo) was a succes or a failure for each patient (attached file).
My quesiton is what chi-square do i need to do in order to determine which drug is better? goodness-of-fit or independence?
I think independence but im not sure...
And also if anyone can help me with the null and the alternative hypothesis, cause i have no idea what to write :\
THANKS A LOT!!!!
