Final answer:
A fictitious experiment can be designed to test the hypothesis that people in a bar will be more likely to leave the bartender tips if the tip jar already has some money in it. The experiment would involve randomly assigning bars to have money in the tip jar or not, and collecting data on the amount of tips left by customers. The experiment is a correlational study.
Step-by-step explanation:
A fictitious experiment can be designed to test the hypothesis that people in a bar will be more likely to leave the bartender tips if the tip jar already has some money in it. The hypothesis is that the presence of money in the tip jar increases tipping. In this experiment, the independent variable would be the presence or absence of money in the tip jar, and the dependent variable would be the amount of tips left by customers.
To conduct the experiment, we can randomly assign bars to either have money in the tip jar or not. Then, we can collect data on the amount of tips left by customers in each bar over a certain period of time. By comparing the average tips in bars with money in the tip jar to the average tips in bars without money in the tip jar, we can determine if there is a relationship between the presence of money and tipping behavior.
It is important to note that this experiment is a correlational study, as it does not involve manipulating the independent variable. Instead, it examines the relationship between two variables and determines if they are related or not.
