O Do Not Reject Ha QUESTION 9 Avandia is an anti-diabetic drug and like all drugs, it can have side effects. One study of patients with congestive heart failure, but taking Avandia for diabetes, found that 5 of the 110 subjects randomly assigned to Avandia died of a cardiovascular event during the study. This compared to 4 of the 114 subjects assigned to the placebo dying of a cardiovascular event. At a 95% level of confidence, is there evidence that a higher proprtion patients taking Avandia died of a cardiovascular event versus the placebo? Let Group 1 = Avandia group and Group 2 = Placebo group. What is the conclusion resulting from this hypotheses test? O At a 95% level of confidence, there is sufficient evidence that a higher proprtion patients taking Avandia died of a cardiovascular event versus the placebo. O At a 95% level of confidence, there is insufficient evidence that a higher proprtion patients taking Avandia died of a cardiovascular event versus the placebo. O At a 95% level of confidence, there is sufficient evidence that more people die after taking Avandia. O At a 95% level of confidence, there is sufficient evidence that more people die after taking the placebo
