Textbook Question
Chapter 9.5, Problem 8E
In a 2p design with one replicate per treatment, it sometimes happens that the observation for one of the treatments is missing, due to experimental error or to some other cause. When this happens, one approach is to replace the missing value with the value that makes the highest-order interaction equal to 0. Refer to Exercise 7. Assume the observation for the treatment where A, B, and C are all at their low level (–1) is missing.
- a. What value for this observation makes the three-way interaction equal to 0?
- b. Using this value, compute estimates for the main effects and the interactions.

A study was conducted at George Mason University to determine a possible optimum level of fertilization, based on the enhanced vertical growth response of the chrysanthemums. Forty chrysanthemum seedlings were divided into four groups, each containing 10 plants. Each was planted in a similar pot containing a uniform growth medium. To each group of plants an increasing concentration of Mg,NH4PO4, measured in grams per bushel, was added: 50 g/bu, 100 g/bu, 200 g/bu, and 400g/bu. The sample means for each group was 15.34 cm, 17.16 cm, 18.3 cm, and 20.1 cm, respectively. Here SST = 758.035. (a) Construct the ANOVA table.
