E
typically referred to as REM sleep (Rapid Eye Movement). You are interested in the
effects a new dream-enhancing drug has on dreaming since an increase in the time
spent dreaming while
sleeping is thought to be a good thing in terms of getting a "restful" sleep. You want
to pursue
testing the drug in humans if there is any evidence that it significantly increases
nightly dreaming time in these nonhuman primates. Ten rhesus monkeys are
administered the drug in the morning and their dream time (in minutes) is monitored
that night. The alternate hypothesis is: the drug will increase time spent dreaming, or
the time in REM sleep. You obtain the following times (minutes) each monkey spent
dreaming:

O The researcher should retain Ho and conclude that the new drug increases time in REM sleep.
