Use the table below to answer the following questions.

Source df SS MS
A 1 136 1.36
B 1 0.622 0.622
A*B 1 22.405 22.405
Error 132 143.948 1.091
Total 135 168.335 x

a) How many levels are there for factor A?  
b) How many levels are there for factor B?

c) At ?=0.05α=0.05, is there evidence of a treatment effect?
(Write step 1 exactly as it appears in the formula packet)
1. ?0H0 :  vs ??Ha :  
2. ?α = 0.05
3. F =  
4. ??Fα =  
5. Conclusion:
Reject H0
Fail to reject H0
Interpretation:
There is sufficient evidence to support that there is a treatment effect.
There is not sufficient evidence to support that there is a treatment effect.

d) Should you test for an interaction effect?
No
Yes
