Example: Sasha is trying to convince her mother to change her bedtime on school nights. She gathers
data on the average number of hours of sleep that a random sample of seventh-grade students in her
school get each night. Will Sasha be able to convince her mother to let her go to bet later?
(Note: On school days, Sasha goes to bed at 9:00 pm. She wakes up at 6:30 am. Q1: How long does she
sleep?) =_8hrs 30mins
This is the data that Sasha gathers: The first row is the sleep duration. The second row is the numbers of
people she asks. 1023445231
