REM (rapid eye movement) sleep is sleep during which most dreams occur. Each night a person has both REM and non-REM sleep. However, it is thought that children have more REM sleep
than adultst. Assume that REM sleep time is normally distributed for both children and adults. A random sample of n, = 9 children (9 years old) showed that they had an average REM
sleep time of x, = 2.9 hours per night. From previous studies, it is known that o, = 0.9 hour. Another random sample of n, = 9 adults showed that they had an average REM sleep time of
2.00 hours per night. Previous studies show that a, = 0.7 hour. Do these data indicate that, on average, children tend to have more REM sleep than adults? Use a 1% level of
significance.
