Donkey wants to learn whether plants with blue flowers and red thorns help wounds to heal. He administers the plants to wounds on an SRS of 40 injured creatures and a placebo to a SRS of 36 injured creatures. Then he measures how long it takes for the wounds to heal. In the end of the study, Donkey finds no substantial difference in the healing time between wounds treated with the plant compared to those treated with the placebo. Identify the statement below that is false. The treatments in Donkey's study are the blue flowers with red thorns, and the placebo. The outcome variable in Donkey's study is that the plants do not help wounds heal faster. Donkey conducted a randomized experiment. The type of wound treated could be a confounding variable in Donkey's study.
