PROBLEM 3 – Correlated groups t-test A researcher wants to test the effectiveness of Prozac on the well-being of depressed individuals. A researcher asks nine participants to complete a well-being survey the first day they start taking Prozac. The researcher then reassesses their well-being after being on the medication for six weeks. Higher scores indicate greater well-being. Use the data below to run a correlated groups t test to test the hypothesis that taking Prozac improves the participants well-being scores. Use this information to answer questions 3a-3f below.

Problem 1 – One-Sample t-test A professor is interested in the study habits of full-time students at a university. The researcher wants to know if students study the recommended minimum of one hour of outside class study time for each hour spent in class. To test his prediction the researcher surveys 10 students and asks the students how many hours they typically study in a week. All of the students are enrolled in 5, 3-unit courses, so the students should study at least 15 hours per week outside of class. Use this information to answer questions 1a-1f below.
