Survival in the ICU and Infection

In the dataset ICUAdmissions, the variable Status indicates whether the ICU (Intensive Care Unit) patient lived (0 ) or died (1 ), while the variable Infection indicates whether the patient had an infection (1 for yes, 0 for no) at the time of admission to the ICU.

Use technology to find a 95% confidence interval for the difference in the proportion who die between those with an infection and those without. (pI-pN)
