Answer :
Answer and Explanation: The data does support the advertisement made by the product. The subject using normal hair removal cream reported 30 days of baldness, while the subject using the advertised product reported 45 days of baldness, which is indeed 50% longer in duration than the other hair removal product.
The control group of the experiment is subject A, who used original hair removal cream. The control group of the experiment is the group that is not exposed to the independent variable, or the group that is not exposed to the experimental treatment, which in this case is the advertised hair removal cream. Subject A used a different hair removal cream in order to test whether the new product's advertisement was true compared to other hair removal products.
The independent variable is the type of hair removal product used by each participant. In an experiment, the independent variable is the variable being manipulated by the researchers in order to determine its effect on the dependent variable. The independent variable is the variable that is different among all experimental groups. In this case, each subject is using a different hair removal product, so the type of hair removal product used is the independent variable.
The dependent variable is the duration of baldness. In experiments, the dependent variable is the variable that is being collected and measured in the experiment. In this case, Patrick is tracking how long each subject remains bald. Thus, the duration of baldness is the dependent variable in this experiment.
