A random sample of 200 subjects who were part of a much larger study on survival of patients following admission to an adult intensive care unit (ICU) was obtained. Below is a contingency table summarizing the relationship between mortality and whether or not the patient was admitted to the ICU from the emergency room.

Research Question: Are patients more likely to die if admitted to the ICU from the ER?

	Admitted	Not Admitted	Total
Died	37	3	40
Survived	110	50	160
Total	147	53	200

a. Explanatory and Response Variables (categorical or quantitative)

b.Parameter of interest and symbol

c.Hypotheses in symbols

d.Proportions for each group and assign symbols

e.Relative Risk (Admitted/Not Admitted) and interpretation

f.Observed Difference (Admitted - Not Admitted)

g.Calculate a 95% confidence interval for the difference in proportions

h.Interpret this confidence interval in context

i.Based on the 95% confidence interval, we would ___________ the null hypothesis.Briefly explain your decision.

j.Conclusion in Context
