REM (rapid eye movement) sleep is sleep during which most dreams ocur. Each night a person has both REM and non-REM sleep. However, it is theught that chdren have more REM sleep than adtst. Assume that REM seep tme is normally distrib.ted for both chdren and ad.A random sample of n,11children (9 years old) showed that they had an average REM sleep time of x,2.9 hours per night. From prevtous studies, tis known that o,0.5 hour. Another random sample ofn,-11 aduts showed that they had an average REH enp tame of ,2.10 hours per night. Previous studies show that a, = 0.9 hour. Do these data indicate that, on average, chdren tend to have more REM sleep than adults? Use a 1% level of signafcance. a) what is the level of significance? state the null and alternate hypotheses.
