Krusty krabs breath mints
mr. krabs created a secret ingredient for a breath mint that he thinks will "cure" the bad breath people
get from eating crabby patties at the krusty krab. he asked 100 customers with a history of bad breath
to try his new breath mint. he had fifty customers (group a) eat a breath mint after they finished
eating a crabby patty. the other fifty (group b) also received a breath mint after they finished the
sandwich, however, it was just a regular breath mint and did not have the secret ingredient. both
groups were told that they were getting the breath mint that would cure their bad breath. two hours
after eating the crabby patties, thirty customers in group a and ten customers in group b reported
having better breath than they normally had after eating crabby patties.
