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 n1 = 8 children (9 years old) showed that they had an average REM sleep time of X1 = 2.7 hours per night. From previous studies, it is known that o1 = 0.8 hour. Another random sample of /2 = 8 adults showed that they had an average REM sleep time of X2 = 1.80 hours per night. Previous studies show that 02 = 0.6 hour. Do these data indicate that, on average, children tend to have more REM sleep than adults? Use a 1% level of significance. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: M1 = M2; H1: M1 > M2 O Ho: M1 = M2; H1: M1 # H2 O Ho: H1
