Patients were classified according to the clinic they were treated. The contingency table below shows the number of patients (y) that were treated at each clinic and whether they survived. Survived Died Clinic A 49 9 Clinic B 57 18 Clinic C 56 14 The null hypothesis is that survival is independent of the clinic attended. Analyze the data to answer the questions below. A) What is the deviance value to test the alternative hypothesis that the chances of survival depend on the clinic? B) What are the degrees of freedom for the deviance above? C) What is the limit of the critical region for the deviance above for a significance level of 0.05? D) Which statement is correct? There is strong evidence that the chances of survival are not independent on the clinic. We cannot reject the null hypothesis that the chances of survival are independent on the clinic.
