Is there sufficient evidence to support the claim that site has an effect on the amount of pesticide?
A) There is sufficient evidence to support the claim.
B) There is not sufficient evidence to support the claim.
C) Because there is no significant effect from the interaction of age and site. One should not consider the effects of age without considering the effects of site.
