(c)Explain from the data, in language that a reporter can understand,how Hospital B can do better overall even though Hospital A doesbetter for both groups of patients.
Good Condition Hospital A Hospital B Died 6 8 Survived 594 592 Total 600 600Explanation / Answer
a) For good condition The percent of survived in Hospital-A is 594 / 600 = 99% and for Hospital-B 592/600 =98.67% Poor Conditino The percent of survived in Hospital-A is 1443/1500= 96.2% and for Hospital-B 192/200 = 96% From the above two cases we can say that theHospital A has a higher survival rate for both groups ofpatients b) Consider the following table Hospital-A Hospital-B Died 63 16 Survied 2037 784 2100 800 Hospital-A Hospital-B Died 63 16 Survied 2037 784 2100 800 The percent of survived in Hospital-A is 2037/2100= 97% and for Hospital-B 784/800 = 98% From this we can say that Hospital B has ahigher survival rate than Hospital A Hospital-A Hospital-B Died 63 16 Survied 2037 784 2100 800Related Questions
