Poloneicki, Sismanidis, Bland, and Jones (2004) reported that in September 2000 heart transplantation at St. George’s Hospital in London was suspended because of concern that more patients were dying than previously. Newspapers reported that the 80% mortality rate in the last 10 cases was of particular concern because it was over five times the national average. The variable measured was whether or not the patient died within 30 days of the transplant. Although there was not an officially reported national mortality rate (probability of death within 30 days for patients undergoing this procedure), the researchers determined that 15% was a reasonable benchmark for comparison
Research Question: Is the true death rate at this hopsital larger than the national benchmark?
Goals: In this lab, you will
- Investigate a research question through a binomal test of significance
- Investigate factors that impact the strength of evidence against the null hypothesis
