Extracted text: Patients diagnosed with retinopathy (disease of the retina) were admitted into a study where they were randomly assigned to one of the two treatments and monitored for 6 years. The study found that 143 of the 352 patients assigned to the conventional treatment (group 1) showed an improvement of their disease. Whereas 177 of the 363 patients assigned to the intensive treatment (group 2) had improvement of the disease. Suppose you are hypothesizing that the intensive treatment (Group 2) is more effective than the conventional treatment (Group 1) but hypotheses are written in the form of Group 1-Group 2. Conducting a test of significance (at a 5%) with the hypotheses you chose from Question 9, you calculated a p-value equal to which made you decide to O A) 0.9861; fail to reject Ho B) 2.20; fail to reject Ho OC) 0.0139; reject Ho D) 0.0139; fail to reject Ho E) -2.20; reject Ho
