Question is:
Mr Krabs created a secret ingredient for a breath mint that he thinks will cure the bad breath people get from eating crabby patties. He asked 100 customers with a history of bad breath to try his new breath mint. He had 50 customers (Group A) eat a breath mint after they finishes eating a crabby patty. The other 50 (Group B) also recieved a breath mint after they finished the sandich, however, it was just 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 hourse after eating the crabby patty, 30 customers from Group A and 10 customers from Group B reported having better breath than they normally had after eating crabby patties.
