Final answer:
Dr. Turner expects students to study 2 hours per week for this course, but statistical information about average study hours suggests varying figures, with the 30th percentile of college students studying 7 hours per week.
Step-by-step explanation:
Dr. Turner expects that students will study 2 hours per week for this course. Given the information provided, there isn't a clear indication of the exact number of hours expected by Dr. Turner for the course. However, statistical data suggests that college students on average spend less than 20 hours studying per week, with the 30th percentile being as low as 7 hours per week. This aligns with general expectations for study time commitment in a typical college setting. Completing additional analysis of the provided data, such as testing the claim about freshman students' study habits, would require more context-specific information regarding Dr. Turner's expectations.
