# The analysis of variance table for a 3 x 4 factorial experiment, with factor A at three levels and factor B at four levels, and with two observations

Upper level probability

The analysis of variance table for a $$3 \times 4$$ factorial experiment, with factor A at three levels and factor B at four levels, and with two observations per treatment is shown here:
Source, df, SS, MS, F
A, 2, 5.3
B, 3, 9.1
AB, 6,
Error, 12, 24.5
Total, 23, 43.7
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 $$\alpha \alpha=.05$$. 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.
