Question

The calculations for a factorial experiment involving four levels of factor A, three levels of factor B, and three replications resulted in the following data: SST = 275, SSA = 26, SSB = 22, SSAB = 174. Set up the ANOVA table. (Round your values for mean squares and F to two decimal places, and your p-values to three decimal places.)

Total

Test for any significant main effects and any interaction effect. Use α = 0.05.

Find the value of the test statistic for factor A. (Round your answer to two decimal places.)___

Find the p-value for factor A. (Round your answer to three decimal places.)

p-value = ___

State your conclusion about factor A.

Because the p-value > α = 0.05, factor A is significant.

Because the p-value ≤ α = 0.05, factor A is not significant.    

Because the p-value ≤ α = 0.05, factor A is significant.

Because the p-value > α = 0.05, factor A is not significant.

Find the value of the test statistic for factor B. (Round your answer to two decimal places.)___

Find the p-value for factor B. (Round your answer to three decimal places.)

p-value = ___

State your conclusion about factor B.

Because the p-value > α = 0.05, factor B is significant.

Because the p-value > α = 0.05, factor B is not significant.    

Because the p-value ≤ α = 0.05, factor B is significant.

Because the p-value ≤ α = 0.05, factor B is not significant.

Find the value of the test statistic for the interaction between factors A and B. (Round your answer to two decimal places.)___

Find the p-value for the interaction between factors A and B. (Round your answer to three decimal places.)

p-value = _____

State your conclusion about the interaction between factors A and B.

Because the p-value ≤ α = 0.05, the interaction between factors A and B is not significant.

Because the p-value > α = 0.05, the interaction between factors A and B is not significant.    

Because the p-value > α = 0.05, the interaction between factors A and B is significant.

Because the p-value ≤ α = 0.05, the interaction between factors A and B is significant
