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, 4139 survived and were discharged . We want to use a 0.05 significance level to test the claim that the survival rates are the same for day and night. Write the hypothesis H0 and H1, calculate test statistic.

Calculate Critical value; do you reject or support the claim.

a. C.V. = ±1.96; Reject the Claim.

b. C.V. = ±1.96; Support the Claim.

c. H0: P1 = P2 H1: P1≠ P2 Test statistic 18.26

d. H0: P1 = P2 H1: P1<P2 Test statistic 18.26
