Example Problems 1 1. An experiment was installed to test 4 rates of Zn on cabbage. There were 3 replicates and the experiment was installed in a randomized complete block design. The yields are given in the table below. A. Calculate the analysis of variance for this data set and perarm the appropriate F tests. Write the formula for each statistic calculated. E. Subdivide the treatment SS into single df using 2 sets of orthogonal comparisons. C. Calculate the SS for the orthogonal comparisons for trends using the orthogonal comparison method and perform the F tests. D. Interpret the results
