Ms. Lynam just bought a new cereal called Smarty- O's that claims to make kids 25% more attentive in class than Frosted Flakes. To test it, she picks 20 kids in her class randomly and gives 10 Smarty- O's, and the other 10 frosted flakes. At the end of the experiment, 2 of the kids who got Smarty O's did not get any higher grades than usual. The kids who got frosted flakes got the same result. What conclusion can she make from this experiment?
