to each treatment. The following data reflect times to relief (in minutes) after taking the

assigned drug.

Test if there is a significant difference in the mean times among three treatments. Use α =

0.05. (apply ANOVA)

a) State the null and alternative hypothesis.

Null: all means are equal

Alternative: Atleast one mean is different

b) State your conclusion about the hypothesis based on the test statistic and critical value

Reject the hypothesis because there is a huge difference between the 3 treatments and their means

c) Perform multiple comparison test to show whether there are significant differences between the drugs
