TIMED PLEASE HURRY Abby analyzed her research. She found studies showing that high school students should get 8 hours of sleep. However, the 100 high school students she surveyed get an average of only 6 hours of sleep because of late bedtimes and early rising times. She concluded that if students started school at a later time, they would get more sleep.

Which new information would most likely require Abby to adjust her conclusion?

a university study on the time college students prefer to start class
recent research on students’ moods when they do not get enough sleep
a report showing research on what time most high school students go to sleep
research showing data that having a later school start time did not improve students’ sleep habits

When they go to bed and what makes them stay up late

Explanation:

She would most likely need to know what time they go to bed because that could be a large factor in when they sleep. If they go to bed at 9 pm, then they wouldn't really benefit from a later sleep because they only get a few hours of sleep even if school started later. Meanwhile students who go to bed later would certainly benefit from the earlier start time.

Also she would need to know why they go to sleep late. For example, homework makes them stay up late because they need to finish their assignments, work on projects, study, etc. Another example is after school activities, students could arrive home late due to sports and have to eat dinner right as they come back, forcing them to do work late at night.
