The data in the following table present the ratio of the wei

The data in the following table present the ratio of the weights of Fe_2O_3 and CaO for SFCA specimens with several different weight percent\'s of AI_2O_3 C_4S_3. Estimate all main effects and interactions. Construct and ANOVA table. You may give ranges for the P-values. Do the data indicate that there are any interactions between the weight percent of AI_2O_3 and the weight percent of C_4S_3? Explain. Do the data convincingly demonstrate that the Fe_2O_3/CaO ratio depends on the weight percent of AI_2O_3? Do the data convincingly demonstrate that the Fe_2O_3/CaO ratio depends on the weight percent of C_4S_3?
