However, it is thought that children have more REM sleep than adultst. Assumethat REM sleep time is normally distributed for both children and adults. A random sampleof m= 11 children (9 years old) showed that they had an average REM sleep time of x₁ = 2.9 hours pernight. From previous studies, it is known that o₁ = 0.6 hour. Another random sample of m2 = 11 adultsshowed that they had an average REM sleep time of x2 = 2.50 hours per night. Previous studies show that0 2 = 0.5 hour.
