Chapter 01.5 Exercise Question 12

1.5.12

In an article published in theBritish Medical Journal(2004), researchers Poloniecki, Sismanidis, Bland, and Jones reported that heart transplantations at St. George's Hospital in London had been suspended in September 2000 after a sudden spike in mortality rate. Of the last 10 heart transplants, 80% had resulted in deaths within 30 days of the transplant. Newspapers reported that this mortality rate was over five times the national average. To explore more deeply, the researchers went on to look at data from the most recent 361 heart transplantations at St. George's and found that 71 had resulted in deaths within 30 days of the heart transplant procedure.

One can use theOne Proportionapplet to produce the null distribution of sample proportion of deaths assuming the long-run proportion of death is 0.15.
