1. Three different fertilizers are to be applied to ?ve bushes each for three varieties of ?ower plants: gardenia (G), rose (R), and jasmine (J). Create a randomized complete block design. Choose as blocks the different types of plants (G, R, or J).

2. With the following modi?cations, consider Exercise. Three groups of ?ower plants are considered, with each group having nine plants. Group I consists of gardenia (G), group II consists of rose (R), and group III consists of jasmine (J). Of the nine gardenias (group I), three are treated with brand A fertilizer, three with brand B, and three with brand C fertilizer. Other plant types are treated similarly. Here the number of replications is three for each type of fertilizer and for each type of plants. Create a randomized complete block design with three replications.
