Assume that, on the average, normal rhesus monkeys spend an mean of 60 minutes dreaming while sleeping at night (thus, µ = 60 minutes). Time spent dreaming is 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 should the researcher make regarding the drug's effect on REM time? The researcher should retain Ho and conclude that the new drug increases time in REM sleep. The researcher should retain HA and conclude that the new drug increases time in REM sleep. O The researcher should reject Hoand conclude that the new drug increases time in REM sleep.

Question
Assume that, on the average, normal rhesus monkeys spend a mean of 60 minutes dreaming while sleeping at night (thus, μ = 60 minutes). Time spent dreaming is 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.

(Note: The question requires choosing one of these options after conducting appropriate statistical tests.)

In this study, researchers examined the effect of a new drug on the REM sleep duration in rhesus monkeys. Ten monkeys were given the drug, and their dream time in minutes was recorded for a night. The alternative hypothesis (Hₐ) is that the drug increases the time spent in REM sleep. The recorded times spent dreaming were: 52, 69, 74, 60, 67, 65, 69, 55, 63, 68 The researchers were instructed to set the significance level (alpha, α) at 0.01 and proceed with step 4 of the hypothesis testing procedure. The task is to decide the drug's effect on REM sleep time. Here are the options provided for the researcher’s decision: - The researcher should retain H₀ and conclude that the new drug increases time in REM sleep. - The researcher should retain Hₐ and conclude that the new drug increases time in REM sleep. - The researcher should reject H₀ and conclude that the new drug increases time in REM sleep. - The researcher should reject Hₐ and conclude that the new drug does not increase time in REM sleep. - The researcher should retain H₀ and conclude that the new drug does not increase time in REM sleep. (This option is highlighted as the selected response.) The highlighted choice indicates that the researcher should retain the null hypothesis (H₀) and conclude that the new drug does not increase the time spent in REM sleep.
