Suppose there are 115 patients in a clinical trial. Of those, 35 received a real medication and were cured of their illness, 20 received the real drug and were not cured, 28 received a sugar pill (placebo) and were not cured and the remaining received a sugar pill and were cured. When testing (at the 10% level of significance) whether the medication was effective (or thinking about it another way, testing whether getting the medication and being cured is independent or not), if the p-value is .263 then what is your conclusion conerning the null hypothesis of independence?     fail to reject the null hypothesis of independence     reject the null hypothesis of independence
