Discuss the differences between the single t test, the independent t test, and the paired samples t test. State the assumptions of each one and compare how they are different. Most importantly, how are the variables different (the amount and type of variables) between the three tests?

Next, give a real-world example of when you would use single t test, the independent t test, and the paired samples t test. Make sure to state the variables and how they are measured in each example.
