- mline Assume that, on the average, normal rhesus monkeys spend an mean of 60 minutes dreaming while sleeping at night (thus, u 60 minutes). Time spent dreaming is 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: 52, 69, 74, 60, 67, 65, 69, 55, 63, 68 Set alpha at a- .01, and complete step 4 of the hypothesis testing procedure, what decision…Statistics helpK During the 2015 season, the home team won 142 of the 263 National Football League games.
