Twenty randomly selected statistics students were given 15 multiple-choice questions and 15 open-ended questions, all on the same material. The professor was interested in determining if students scored higher on the multiple-choice questions. This experiment is an example of a paired t-test.
Because, in this experiment same 20 students were given 15 multiple-choice questions and 15 open-ended questions.
This type of experiment used a pair t-test.

For questions 5-8, suppose there is a test that consists of 100 multiple choice questions. You have made a study guide for the test, and you are interested in whether the study guide makes any difference in test performance. You administer the test to a randomly selected group of 14 students who have looked at the study guide first (study guide group), and another randomly selected group of 12 students who have not looked at the study guide first (control...
