Medical guidelines recommend that a hospitalized patient who suffers cardiac arrest should receive defibrillation (an electric shock to the heart to restore normal rhythm) within 2 minutes. Medical researchers examined the medical records of 6716 patients who suffered cardiac arrest while hospitalized. Here is what they found: Time to Defibrillation Hospital Size 2 minutes or less More than 2 minutes TOTAL Small (less than 250 beds) 1124 576 1700 Medium (250 – 499 beds) 2178 886 3064 Large (500 or more beds) 1387 565 1952 TOTAL 4689 2027 6716 a. [3 points] State the hypotheses that should be used to test if the relationship between hospital size and time to defibrillation is statistically significant. b. [2 points] The appropriate hypothesis test was conducted and resulted in a p-value of 0.0013. Should the null hypothesis be rejected at the 5% level of significance? Explain why or why not (you may draw a graph to explain). c. [3 points] What is the probability that a hospitalized patient who suffers cardiac arrest will receive defibrillation within 2 minutes? You may leave your answer as a fraction, or report to 3 decimal places. d. [4 points] Given the patient is in a small hospital, what is the probability that it will take more than 2 minutes to receive defibrillation for a cardiac arrest? You may leave your answer as a fraction, or report to 3 decimal places. e. [4 points] Create a 95% confidence interval estimate for the difference in proportion of patients whose time to defibrillation was more than 2 minutes between small and large hospitals.
