Data for exercise: Decreases in body temperature (degrees Fahrenheit)

Group 1 (aspirin)	0.95	1.48	1.33	1.28
Group 2 (ibuprofen)	0.39	0.44	1.31	2.48	1.39
Group 3 (acetaminophen)	0.19	1.02	0.07	0.01	0.62	-0.39

This trial evaluated the fever reducing effects of three substances. Study subjects were adults seen in an emergency room with diagnosis of flu with body temperatures between 100.0 degrees F to 100.9 degree F. The three treatments aspirin, ibuprofen, and acetaminophen were assigned randomly to study subjects. Body temperatures were reevaluated 2 hours after administration of treatments. Display the above data with side-by-side box plots and calculate the mean and standard deviation of each group and describe what you find then produce an ANOVA for the problem.
