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), what is the critical value (please round your answer to 3 decimal places)
