The data in the following table resulted from an experiment that utilized a completely randomized design:

Treatment 1 Treatment 2 Treatment 3 3.9 5.4 1.3 1.4 2.0 .7 4.1 4.8 2.2 LO4 5.5 3.8 2.3 3.5

a. Use statistical software (or the formulas in Appendix B)

to complete the following ANOVA table:

Source df SS MS F Treatments Error Total

b. Test the null hypothesis that m1 = m2 = m3, where mi represents the true mean for treatment i, against the alternative that at least two of the means differ. Use a = .01.
