Which treatment is most effective at treating carpet stains: vinegar, ammonia, or hydrogen peroxide? In a study, researchers randomly assigned 55 carpet samples with identical stains to one of three groups. Depending on which group they were assigned to, each carpet sample received a home remedy of water mixed with vinegar, ammonia, or hydrogen peroxide. Afterwards, each carpet sample was examined and any remaining stain was measured. Researchers found that a vinegar and water mixture produced better results than both ammonia and hydrogen peroxide.
Choose the statement that restates the conclusion of the study in terms of a cause-and-effect conclusion.
◦ A water and vinegar mixture effectively treats carpet stains compared to ammonia and hydrogen peroxide.
◦ The type of treatment received is associated with the amount of stain removed.
◦ People who use water and vinegar to treat carpet stains will have fewer visible carpet stains.
◦ A water and ammonia mixture effectively treats carpet stains compared to ammonia and hydrogen peroxide.
