A study revealed that the 30-day readmission rate was 31.4 percent for 370 patients who received after-hospital care instructions (e.g., how to take their medications) compared to a readmission rate of 45.1 percent for 368 patients who did not receive such information.
(a) Set up the hypotheses to see whether the admissions rate was lower for those who received the information.
(b) Find the p-value for the test.
(c) What is your conclusion at α = .05? At α = .01?
