A simple random sample of n=15 subjects evaluated the fever-reducing effects of three substances. Study subjects were adults seen in an emergency room with diagnoses of flu with body temperatures between 100.0 and 100.9°F. Subjects were randomly assigned to one of three treatment groups (aspirin, ibuprofen, and acetaminophen). Body temperatures were reevaluated 2 hours after administration of treatments. After concluding that at least one group mean was different, the LSD Multiple Comparison test result was performed and is shown below. Which two treatment means are NOT different?
