Patty Power
Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created
a new sauce that he thinks will reduce the production of body gas associated
with eating crabby patties from the Krusty Krab. He recruits 100 customers
with a history of gas problems. He has 50 of them (Group A) eat crabby
patties with the new sauce. The other 50 (Group B) eat crabby patties with
sauce that looks just like new sauce but is really just mixture of mayonnaise
and food coloring. Both groups were told that they were getting the sauce
that would reduce gas production. Two hours after eating the crabby patties,
30 customers in group A reported having fewer gas problems and 8 customers
in group B reported having fewer gas problems.
