Mr. Krabbs wants to make Bikini Bottom a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating his crabby patties. He recruits 100 customers with a history of gas problems. He has 50 (Group A) eat crabby patties with the new sauce, and 50 (Group B) eat crabby patties with a sauce that looks like the new sauce but is really just a mixture of mayonnaise and food coloring. Both groups were told they were getting the sauce that reduces gas production. Two hours later, 30 customers in Group A reported having fewer gas problems and 8 in group B reported having fewer gas problems. 1. Which is the control group?
2. Which is the experimental group?
3. What is the independent variable?
4. What is the dependent variable?
5. What should the conclusion be?
6. Why did 8 people in Group B report less gas?

A. The sauce.

This variable does not depend on any other one. It is the supposed cause of the studied phenomenon and we manipulate it for experimental research.

This variable has 2 treatments: a new sauce that is expected to reduce gas problems and the mixture that looks like the new sauce, that is not expected to make a difference in gas problems.

B. Gas problems.

This variable depends on the independent variable (the one we are manipulating). It is the output that is being researched.

C. Group B (the 50 customers that ate a mixture that looks like the new sauce)

The control group is given a treatment that is not expected to affect gas production, so it serves as a benchmark to compare with other tested groups.

D. The krabby patties.

Both groups ate the krabby patties so the patties should not determine differences in the results.

E. An experimental study.

We are providing different treatments to study groups so we can assess differences in the results attributable to these treatments, so this is an experiment.

Please let me know if this answer is wrong :(

the answer is a) a shiprock was formed by igneous process

no i don't feel that humans have oversubscribed some medications
