Question: The analysis of variance table for a 3 Ã 4 factorial experiment, with factor A at three levels and factor B at four levels, and

The analysis of variance table for a 3 Ã— 4 factorial experiment, with factor A at three levels and factor B at four levels, and with two observations per treatment, is shown here:

a. Fill in the missing items in the table.
b. Do the data provide sufficient evidence to indicate that factors A and B interact? Test using a = .05. What are the practical implications of your answer?
c. Do the data provide sufficient evidence to indicate that factors A and B affect the response variable x? Explain.
