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.
Which people are in the control group?
What is the independent variable?
What is the dependent variable?
What is an appropriate hypothesis?
What should Mr. Krabs’ conclusion be?
Answers
Answer:
Group B is the control group.
The independent variable is the amount of recruited customers.
The dependent variable is the new sauce.
Hypothesis: If customers consume the new Krabby Patty sauce then they will experience fewer gas related problems.
Explanation:
Group B is the control group because they did not receive the new sauce treatment.
The independent variable is the variable that remains the same.
The dependent variable is the variable being tested and measured in an experiment and is 'dependent' on the independent variable.
It is given that Mr. Krabbs recruited 100 customers with a history of gas problems to tate his new sauce which he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty krab.
- Group A consisting of 50 of these customers were given the new sauce while the Group B consisting of 50 were given the old sauce that resembled the new sauce.
- Both groups were told they were consuming the new sauce.
- Which people are in the control group?
Group B were in the control group. They were continued to be given the regular sauce but were told that they are consuming the new sauce.
- What is the independent variable?
New Sauce is the independent variable in the given question. The independent variable is the variable that remains the same.
- What is the dependent variable?
The dependent variable is the variable being tested and measured in an experiment and is 'dependent' on the independent variable. Amount of production of body gas associated with eating crabby patties from the Krusty krab is the dependent variable here.
- What is an appropriate hypothesis?
Hypothesis: If customers consume the new crabby Patties sauce then they will experience fewer gas related problems.
- What should Mr. Krabs’ conclusion be?
30 customers in group A reported having fewer gas problems
8 customers in group B reported having fewer gas problems
The new sauce does the job.
It reduced the production of body gas that was associated with eating crabby patties from the Krusty Krab.
