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 krabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat krabby patties with the new sauce. The other 50 (Group B) eat krabby patties with sauce that looks just like the 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 krabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.

Which group is the control group?

Patrick believes that fish that eat food exposed to

microwaves will become smarter and would be

able to swim through a maze faster. He decides

to perform an experiment by placing fish food in

a microwave for 20 seconds. He has the fish

swim through a maze and records the time it

takes for each one to make it to the end. He feeds

the special food to 10 fish and gives regular food

to 10 others. After 1 week, he has the fish swim

through the maze again and records the times for

each.
