E, none of the above 13, Trevor runs an experiment on a newly developed drug for insomnia Trevor assigns one group of 15 patients to receive the drug and another group of 15 patiems to receive a placebo. He measures the average hours of sleep between the two and runs an independent t-test to see if the groups are Trevor uses atwo-level weit with a p of 0.05. If Trevor finds a of 201, what will Be careful. The entire statement has to be true to be the correct answer. There is only one correct answer here). A. He will reject Ho and conclude that the groups were significantly different from one another B. He will fail to reject Ho and conclude that the groups are different from one another. C. He will reject Ho and conclude that the groups were not different from one another D. He will fail to reject Ho and conclude that the groups were not different from one E. None of the above 14. Which statement(s) accurately describe characteristics of an ANOVA test? A. The F statistic will be larger if there is more within group variation than between group variation B. The test compares a single mean to a population. C. The test works best when subjects are counted in multiple groups. D. The F statistic will be negative if there is more error than variation between groups None of the above A population has a mean (u) of 24.12 and a standard deviation (o) of 4.
