A study investigated survival rates for in-hospital patients who suffered cardiac arrest. Among 58,593 patients who had cardiac arrest during the day, 11,604 survived and were discharged. Among 28,155 patients who suffered cardiac arrest at night, 4,139 survived and were discharged. We want to use a 0.01 significance level to test the claim that the survival rates are the same for day and night. For full credit, state the hypotheses, test statistic, p value, your decision (with a reason), and conclusion statement.   Use the P-value method.
