Answer
Factor A: P-value $=0.579$
There is not enough evidence to conclude that $µ_{Level~1}\neµ_{Level~2}$
Factor B: P-value $=0.021$
There is enough evidence to conclude that at least one of the means differs.
Work Step by Step
Factor A:
$H_0:µ_{Level~1}=µ_{Level~2}$ versus $H_1:µ_{Level~1}\neµ_{Level~2}$
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 $=0.579$
Factor B: P-value $=0.021$
