Testing Claims About Proportions. In Exercises 718, test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, Pvalue or critical value(s), conclusion about the null hypothesis, and final conclusion that addresses the original claim.Cardiac Arrest at Day and Night A study investigated survival rates for inhospital patients who suffered cardiac arrest. Among 58,593 patientswho had cardiac arrest during the day, 11,604 survived and were discharged. Among 28,155 patients who suffered cardiac arrest at night, 4139survived and were discharged (based on data from Survival from InHospital Cardiac Arrest During Nights and Weekends, by Peberdy et al., Journal of the American Medical Association, Vol. 299, No. 7). We want touse a 0.01 significance level to test the claim that the survival rates are the same for day and night.a. Test the claim using a hypothesis test.b. Test the claim by constructing an appropriate confidence interval.c. Based on the results, does it appear that for inhospital patients who suffer cardiac arrest, the survival rate is the same for day and night?
