We would like to find out if study environment makes a difference in test scores. To do so, we randomly assign 20 students into two groups. Group 1 studies in a quiet library, and Group 2 studies in a noisy coffee shop. Each group studies for 2 hours and then takes the test. The scores are presented in the "study environment" worksheet. Use an appropriate statistical tool to answer this question: Do students who study in quiet environments perform better on tests than those who study in noisy environments?
