1.A trial evaluated the fever-inducing effects of three substances. Study subjects were adults seen in an emergency room with diagnoses of the flu and body temperatures between 100.0 and 100.9F. The three treatments (aspirin, ibuprofen and acetaminophen) were assigned randomly to study subjects. Body temperatures were reevaluated 2 hours after administration of treatments. The below table lists the data.

Iata Table: Decreases in body temperature (degrees Fahrenheit) for each patient m mM__- m-- (ibuprofen) m (acetaminophen) The ANOVA table that corresponds to this data is below. a) State the research question that this ANOVA answers. b) Answer your research question using the means in the Data Table and the ANOVA results. c) Which treatment(s) would you recommend to reduce a fever for this population? d) What type of tests could you conduct that would allow you to compare each treatment group to the other (2 at a time) without inflating the type I error (ct)? e) Why is it important to make sure you do not increase the type I error?
