The article “Organic Recycling for Soil Quality Conservation in a Sub-Tropical Plateau Region” (K. Chakrabarti, B. Sarkar, et al., J. Agronomy and Crop Science, 2000:137-142) reports an experiment in which soil specimens were treated with six different treatments, with two replicates per treatment, and the acid phosphate activity (in μmol p -nitrophenol released per gram of oven-dry soil per hour) was recorded. An ANOVA table for a one-way ANOVA is presented in the following box.
The treatment means were
a. Can you conclude that there are differences in acid phosphate activity'among the treatments?
b. Use the Tukey-Kramer method to determine which pairs of treatment means, if any, are different at the 5% level.
c.use the Bonferroni method to determine which pairs of treatment means, if any, are different at the 5% level
d.Which method is more powerful in this case, the Tukey-Kramer method or the Bonferroni method?
e.The experimenter notices that treatment A had the smallest sample mean, while treatment B had the largest. Of the Fisher LSD method, the Bonferroni method, and the Tukey-Kramer method, which, if any, can be used to teSt the hypothesis that these two treatment means are equal?
