Hay Fever Relief Data: A research laboratory was developing a new compound for the relief of severe cases of hay fever. In an experiment with 36 volunteers. the amounts of the two active ingredients (factors A and B ) in the compound were varied at three levels each. Randomization was used in assigning four volunteers to each of the nine treatments. The data on hours of relief follow. Factor B (ingredient 2) j=1 Low j = 2 Medium j= 3 High Factor A (ingredient 1) i = 1 Low 2.4 4.6 4.8 2.5 4,7 4.6 i = 2 Medium 5.8 8.9 9.1 5.3 9.0 9.4 i = 3 High 6.1 9.9 13.5 ... 6.2 10,1 13.2 Use the corresponding SAS output to answer each of the following questions. 1.
