I have to do this problem for my high school stats class. I have no idea where to start. Can someone please show me how to do this and help me find out the answers? Thanks.
The following table was taken from a report on the relationship between aspirin use and myocardial infarction by the Physician’s Research Group at Havard. The physician’s study was a 5-year randomized study testing whether regular intake of aspirin reduces mortality from cardiovascular disease. Every day, physicians participating in the study either took one aspirin or a placebo. The study was blind. The results of the study were actually published well before the study ended. Based on the data, explain why the doctor’s running the study published their results early. Justify your position.
Myocardial Infarction
Aspirin- Yes(104) No(10933)
Placebo- Yes(189) No(10845)
1. Produce a 95% confidence interval for the difference of proportions between the Aspirin group that had heart attacks and the Placebo group that had heart attacks (Myocardio Infarction=yes)
2. Produce a 95% confidence interval for odds ratio of Aspirin group that had heart attacks to the Placebo group that had heard attacks (Myocardio Infarction).
3. Does the interpretation of these two confidence intervals agree with each other? Justify why or why not?
