Question

Antipyretics trail. A trail 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 F to 100.9 F. The three treatments (asprin, ibuprofen, and acetaminophen) were assigned randomly to study subjects. Body temperatures were reevaluated 2 hours after administration of treatments. Table 13.14 lists the data.

(a) Explore these data with side by side boxplots. Discuss your findings.
(b) Calculate the mean and standard deviation of each group.

Table 13.14 Data for Exercise 13.9. Decreases in the body temperatures (degrees Fahrenheit).
Group 1 (asprin):                  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

(C ) Complete an ANOVA for the problem. What do you conclude?
