Final answer:
Dr. Baker's experiment aims to establish a cause-and-effect relationship between lab rats' consumption of energy drinks and their problem-solving abilities. Two possible scientific questions for further experimental testing could focus on the effects of energy drink consumption on problem-solving and the dose-response relationship.
Step-by-step explanation:
Dr. Baker's experiment concerning lab rats' reaction to energy drinks in relation to problem-solving is primarily interested in the goal of establishing cause and effect. This is because the experiment aims to determine whether the energy drinks have a causal effect on the rats' problem-solving abilities. In scientific research, establishing a cause-and-effect relationship is achieved through controlled experimentation, where one or more variables are manipulated to observe the effect on a dependent variable. Once the data are collected, researchers aim to conclude whether the changes in the independent variable (like consumption of energy drinks) caused any observed differences in the dependent variable (such as problem-solving capabilities).
As for the two scientific questions that Dr. Baker could test experimentally, they might be: (1) Does the consumption of energy drinks improve the problem-solving abilities of lab rats compared to a control group with no energy drink? (2) Is there a dose-response relationship between the amount of energy drink consumed and the proficiency in problem-solving among lab rats?
