For many adolescents in high school, obtaining adequate sleep can be difficult. One proposed way to increase sleep duration for teens is to delay the school start time. In one study, the school schedule was modified. The study was conducted at a residential boarding school, where students lived at the school site rather than at home. For Fall term (Time 1), the schedule was 8am-6pm on Mondays, Tuesdays, Thursdays and Fridays and 8am- 12:35pm on Wednesdays and Saturdays. For Winter term (Time 2), the schedule was changed to 8:25am-5:35pm on Mondays, Tuesdays, Thursdays, and Fridays and 8:25am to 12:35pm on Wednesdays and Saturdays. Boarding students completed surveys at the end of Fall term (Time 1), and at the end of Winter term (Time 2). The chart below presents the answers to one question students were asked in their survey, about how much sleep they got at night during the term. % of students 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% End of Fall Term (8 am Start Time) 8+ Hours of Sleep ■< 8 Hours of Sleep End of Winter Term (8:25 am Start Time) School Start Time Approximately what percentage of students reported getting 8 hours of sleep or more when the school day started earlier?

on Mondays, Tuesdays, Thursdays, and Fridays and 8:25am to 12:35pm on Wednesdays and Saturdays. Boarding
students completed surveys at the end of Fall term (Time 1), and at the end of Winter term (Time 2).
