A researcher believes that drinking chamomile tea before bed can affect the amount of sleep a person gets. To test this, the researcher measures the amount of sleep for 15 individuals for a week without tea and then another week with chamomile tea before bed. The data collected include the average hours of sleep per night for each participant in both conditions. Conduct a paired samples t-test to see if chamomile tea has a significant effect on sleep duration.

Step 1
The alternative hypothesis (H1) is that there is a difference in the average amount of sleep between the two conditions. H0: μ_without_tea = μ_with_tea H1: μ_without_tea ≠ μ_with_tea Show more…

A researchers is interested in the amount of sleep an individual receives after consuming a sleeping aid (Melatonin, Valerian root, and Placebo). The researcher randomly selects individuals into either group. However, some individuals drop out of the study which results in unequal sample sizes. Melatonin: n=6, M=14, T=84, SS=60 Valerian: n=10, M=13, T=130, SS=90 Placebo: n=4, M=9, T=36, SS=37 N=20, G=250, x2=3377 State the conclusion of these findings.

Consider the results of a clinical trial to test the effectiveness of a sleeping drug in which the sleep patterns of 5 patients were observed. Each patient was given the drug for one night and a placebo for another, and their sleep times, in hours, were recorded. $$\begin{array}{llllll}\text { Patients } & 1 & 2 & 3 & 4 & 5 \\\hline \text { Placebo } & 4 & 8 & 7 & 4 & 9 \\\text { Drug } & 9 & 10 & 6 & 8 & 9\end{array}$$ Use the signed-rank test for paired observations to test the hypothesis that at the 0.05 level of significance, the drug has no effect on a person's sleep against the alternative that sleeping hours increase if the patient uses the drug.

A longitudinal study is performed to evaluate the efficacy of melatonin supplements for reducing sleeplessness. Sleep patterns for 10 subjects were recorded before and after taking supplements and the following data shows total number of poor-quality sleep during a 30 -day period: a) Compute a 95% confidence interval for the mean difference in poor-quality sleep hours. b) What is the optimal statistical method to evaluate whether melatonin improved sleep quality? Justify your answer. c) Perform your statistical evaluation from 3(b). d) Interpret the outcomes of 3(c)- do the results of 3(a) and 3(c) provide the same information?
