Pain Relief Response Time Passage One
A medical experiment was structured so that five trials could be conducted independently in five different laboratories.
20 subjects in each trial were randomly assigned to receive different doses of an experimental pain reliever. Response time
refers to the number of seconds it takes for the subject to push a button recording when they experienced any feeling of
relief. Instead of referring to the laboratories conducting the research by name, the oversight committee has identified the
trials using the numbers 1 - 5.
Pain Relief Response Time Passage Two
One of the principle researcher's motivations is to gather information about the laboratories conducting his research. Previous
trials have established that the pain reliever works in most patients within 900 seconds at almost any dose above 1mg. If in any
single trial more than 15% of the subjects report response times greater than 900 seconds, the researcher will order his
students to perform a procedural audit of the lab which performed that trial.
Two of the labs will be audited.
No dose of less than 10 mg resulted in pain relief in less than 750 sec
The median time until relief in Trial 2 is close to 845 seconds
