2. An experiment is conducted in which four treatments are to be compared in five blocks. The following data are generated: Block Treatments 1 2 3 4 1 12.8 10.6 11.7 10.7 11.0 2 11.7 14.2 11.8 9.9 13.8 3 11.5 14.7 13.6 10.7 15.9 4 12.6 16.5 15.4 9.6 17.1 Test the hypothesis at the 0.05 level of significance that there is no difference between treatment means. This time, instead of using a fixed-effects model, assume a random-effects model.
