Extracted text: 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 = 2 Medium j = 3 High Factor A j=1 Low (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. Does this estimated treatment means plot suggest that any factor effects are present? Explain.
