QUESTION S:The following data were generated from a where factor A levels represent two different injecti (located in the back of the neck), and factor B levels represent two different drugs recommend to increase the effectiveness of the injections. Three headache patients were for each combination of injection and drug.

Solving question 1 ,
Treatment Mean : Since p-value of 0.0330 < 0.05, the effect is significant an differences exist between treatment means.
Factor A Since p-value of 0.2995 >0.05, the effect is significant and we cannot say with confidence that levels of factor A are signiciant.
Interaction:Since p-value of 0.0069<0.05, the effect is significant and we cannot say wit 95% confidence that interaction is present between A and B
Factor B :Since p-value of 0.5943 >0.05, the effect is significant and we cannot say with confidence that levels of factor B are signiciant.
