Answer
Factor A: P-value $=0.037$. Reject the null hypothesis.
There is enough evidence to conclude that at least one of the means differs.
Factor B: P-value $=0.858$ Do not reject the null hypothesis.
There is not enough evidence to conclude that at least one of the means differs.
Work Step by Step
Factor A:
$H_0:µ_{Level~1}=µ_{Level~2}=µ_{Level~3}$ versus $H_1:$ at least one of the means differs
Factor B:
$H_0:µ_{Level~1}=µ_{Level~2}=µ_{Level~3}$ versus $H_1:$ at least one of the means differs
Use the results obtained in item (a):
Factor A: P-value $=0.037$
Factor B: P-value $=0.858$
