Answer
Age: P-value $=0.042$
There is enough evidence to conclude that at least one of the means differs.
Diet: P-value $\lt0.001$
There is enough evidence to conclude that at least one of the means differs.
Work Step by Step
Age:
$H_0:µ_{20-29}=µ_{30-39}=µ_{40~or~older}$ versus $H_1:$ at least one of the means differs
Diet:
$H_0:µ_{Diet~1}=µ_{Diet~2}=µ_{Diet~3}$ versus $H_1:$ at least one of the means differs
Use the results obtained in item (b):
Age: P-value $=0.042$
Diet: P-value $\lt0.001$
