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 the questions below.
